In this statement and conclusion question, you are given a conditional statement about hard work and success. You must treat the statement as true and decide which conclusions I and II logically follow. Statement: If he works hard, he will be successful in life. Conclusion I: He is a hard worker. Conclusion II: Hard work pays.

Introduction / Context:
This problem uses a simple conditional statement about hard work and success to test your understanding of what can and cannot be logically inferred. The statement has the structure "If he works hard, then he will be successful." From this, you must judge whether it follows that he actually is a hard worker and whether it follows that hard work is effective in achieving success.

Given Data / Assumptions:
- Statement: If he works hard, he will be successful in life. Symbolically, if H then S, where H stands for "he works hard" and S stands for "he is successful."
- Conclusion I: He is a hard worker, which asserts H is true.
- Conclusion II: Hard work pays, which is a general interpretation that hard work leads to success.

Concept / Approach:
The logical form of the statement is a conditional. A conditional tells us what happens if the condition holds, but it does not by itself tell us that the condition actually holds. To claim that he is a hard worker would require evidence that H is true, not only that H implies S. However, the statement does express a belief in a cause effect relationship between hard work and success. That belief can be interpreted as a general principle that hard work is rewarded with success, which aligns with Conclusion II.

Step-by-Step Solution:
Step 1: The statement "If he works hard, he will be successful" tells us: whenever he works hard, success in life follows. Step 2: This is a conditional promise or rule. It says nothing directly about whether he actually works hard. Step 3: Therefore, we cannot conclude from this alone that he is currently a hard worker, so Conclusion I does not logically follow. Step 4: The statement clearly expresses the idea that there is a positive relationship between hard work and success. Essentially, it claims that hard work leads to success for this person. Step 5: Conclusion II, "Hard work pays," is a concise way of summarizing this cause effect relationship: if someone works hard, success results. Step 6: Because the given conditional explicitly states that working hard is sufficient for success, Conclusion II is logically supported as an interpretation of the principle behind the statement.

Verification / Alternative check:
Think of the statement as a rule like "If you press the switch, the light will turn on." This rule does not tell you that you have pressed the switch, only what will happen if you do. Similarly, "If he works hard, he will be successful" does not assert that he is working hard now. However, it does express that hard work is effective in producing success for him. In everyday language, this is exactly what people mean when they say that hard work pays off.

Why Other Options Are Wrong:
Option A says both conclusions follow, but we have seen that Conclusion I does not follow from a conditional statement without additional information. Option B says only Conclusion I follows, which gets the logic backwards. Option D says neither follows, which ignores the clear general principle contained in the conditional. Option E claims Conclusion II is only an assumption, but it is in fact a direct restatement of the idea that if he works hard then he will be successful.

Common Pitfalls:
A very common error is confusing "if H then S" with "H is true." Many learners assume that having a rule implies the condition is already in effect, which is logically incorrect. Another pitfall is to treat Conclusion II as too general, but note that the statement is framed as a reliable connection between hard work and success in his life, which is precisely what the phrase "hard work pays" expresses in informal language.

Final Answer:
The correct option is Only II follows, because the statement supports the idea that hard work leads to success, but it does not guarantee that he is currently or habitually working hard.
