In the following question, a word has been written in four different ways out of which only one is correctly spelt. Select the correctly spelt word.

Introduction / Context:
This spelling question asks you to identify the correct spelling of a word that describes hostile or violent behaviour. The options contain common types of spelling mistakes such as doubling the wrong consonants or omitting letters. Recognising the correct form of frequently tested words is important for error free writing and for scoring well in objective English tests.

Given Data / Assumptions:

• All four options are variants of the word meaning hostile or attacking behaviour.
• The standard spelling in English is aggression.
• Options: Aggrression, Aggrresion, Aggression, Agrresson.

Concept / Approach:
The correct spelling aggression has two g letters and two s letters, arranged as a double g followed by a single r and then a double s: a g g r e s s i o n. Many spelling distractors repeat letters in the wrong place or drop vowels. To answer correctly, you should mentally break the word into syllables and check the pattern ag gress ion, where gress is the core part also seen in words like aggressor and digression with similar consonant patterns.

Step-by-Step Solution:
Step 1: Recall or look up mentally the standard spelling of the word aggression: a g g r e s s i o n.Step 2: Compare each option with this mental template.Step 3: Option C, Aggression, matches exactly: a g g r e s s i o n.Step 4: Option A, Aggrression, has three consecutive r letters after the double g, which is incorrect and looks visually excessive.Step 5: Option B, Aggrresion, has a double r but only a single s, so the core gress part is misspelt.Step 6: Option D, Agrresson, moves one g away and also distorts the placement of vowels, producing a non standard form.

Verification / Alternative check:
Think of related words to cross check the consonant pattern. The noun aggression relates to the adjective aggressive and the noun aggressor. Aggressive is spelt a g g r e s s i v e, and aggressor is a g g r e s s o r. In both cases there is a double g followed by a single r and a double s. The base unit gress stays constant. This confirms that aggression must follow the same pattern, making Aggression in option C the only correct spelling.

Why Other Options Are Wrong:
Aggrression: This form has an extra r, giving g g r r, which has no support in any related English word. Aggrresion: Here the double consonant is r r and there is only one s, which breaks the common pattern gress. Agrresson: This version loses one g and also misplaces the vowels, creating a form that does not match any standard English word. All three are typical exam distractors designed to confuse test takers who are unsure of where the double letters go.

Common Pitfalls:
Spelling questions often rely on the confusion caused by pairs of repeated consonants. Learners may remember that the word has doubles but forget exactly where. Some may over correct by adding too many repeated letters, while others may under correct and remove necessary ones. A good strategy is to memorise a small set of high frequency tricky spellings, especially words commonly used in exams like aggression, occasion, accommodate and necessary. Using families of words, for example, aggression, aggressor and aggressive, also helps fix the pattern in your memory.

Final Answer:
The correctly spelt word is Aggression, which appears as option C.
