The question below consists of four labelled sentences. Out of the given options, select the most logical order of the sentences (P, Q, R, S) to form a coherent paragraph about the environment and our responsibility towards it.

Introduction / Context:
This question tests your ability to arrange jumbled sentences into a clear and logically flowing paragraph. The four parts all discuss the environment, how it supports human life and why it needs protection. In paragraph ordering questions, you must pay attention to sequence markers, pronouns and the general movement from definition to explanation and finally to conclusion or appeal.

Given Data / Assumptions:

• P: However, our environment also need some help from all of us to get maintained as usual to nourish our lives forever and to never ruin our lives.
• Q: It gives us all things which we need to live our life on this planet.
• R: It provides us better medium to grow and develop.
• S: An environment includes all the natural resources which surround us to help in number of ways.
• Exactly one of the four given sequences (PQRS, QPSR, SRQP, QSPR) forms a smooth paragraph.

Concept / Approach:
A good paragraph usually starts with a general definition or introduction, then moves to explanations or examples, and finally concludes with a contrast, warning or suggestion. Among the sentences, S clearly defines environment, so S is a natural opening. Sentences Q and R talk about what the environment gives us and how it helps us grow, which should come after the basic definition. Sentence P begins with However and appeals for human help, which sounds like a concluding remark. Our task is to choose the sequence that follows this logical structure. The order S R Q P is acceptable and is the best among the supplied options.

Step-by-Step Solution:
Step 1: Identify the introductory sentence. S defines environment as including all the natural resources that surround us. This is clearly the starting point because no other sentence introduces the main topic as clearly. Step 2: Decide what can follow S. After defining environment, we should talk about what it does for us. Both Q and R begin with It and refer back to environment, so they can only come after S. Step 3: Compare R and Q for the second position. R says It provides us better medium to grow and develop. Q says It gives us all things which we need to live our life on this planet. Either could follow, but placing R immediately after S maintains a general developmental idea, followed by the more specific point in Q about things we need to live. Step 4: Place Q next. Q clearly continues the idea of environmental support by specifying that it gives us all things we need to live. Step 5: Place P last. P begins with However and speaks of our duty to help maintain the environment, which sounds like a concluding or contrasting remark after describing all the benefits we receive. Step 6: The resulting order is S R Q P, which corresponds to option SRQP in the answer choices.

Verification / Alternative check:
Read the paragraph in the SRQP order: An environment includes all the natural resources which surround us to help in number of ways. It provides us better medium to grow and develop. It gives us all things which we need to live our life on this planet. However, our environment also need some help from all of us to get maintained as usual to nourish our lives forever and to never ruin our lives. Even though the grammar needs small corrections, the logical flow is clear: definition, benefits, further benefits, and then an appeal for protection. None of the other orders produce such a natural sequence.

Why Other Options Are Wrong:
PQRS starts with However, which normally cannot open a paragraph because it refers back to an earlier idea that has not yet been mentioned.
QPSR begins with a sentence using It, but without a clear noun before it, the reference is vague; moreover, P should not come so early, as it is a concluding appeal.
QSPR again begins with It, has P as the third sentence, and leaves R for the end, producing a less coherent flow and a weak conclusion.

Common Pitfalls:
Many students try to memorise fixed patterns without reading the actual content. In paragraph ordering questions, it is essential to read for meaning and to notice connecting devices such as pronouns and words like however, therefore and thus. Pay attention to which sentence introduces the topic, which ones provide supporting information, and which one expresses a conclusion or contrast. That habit will guide you to the correct order even when grammar or phrasing is slightly imperfect.

Final Answer:
The most logical order of the sentences is SRQP, corresponding to option C.
