In this English spelling question, select the correctly spelt form of the word that means violent behaviour or intense hostility.

Introduction / Context:
Spelling questions in competitive exams check your familiarity with common but often misspelt English words. The word tested here refers to angry, hostile, or violent behaviour and appears in subjects such as psychology, politics, and everyday news reports. Choosing the correct spelling requires you to remember standard patterns in English word formation, especially the correct number and placement of repeated consonants.

Given Data / Assumptions:

• The word is pronounced similar to aggression.
• Options use different patterns of the letters g, r, e, s, i, o, n.
• Only one option reflects the standard dictionary spelling.
• The context suggests hostile or violent behaviour.

Concept / Approach:
The correct spelling of the word is aggression, with a double g and double s. Many English words derived from the Latin root aggredi or related forms follow a pattern with double consonants, and aggression fits this pattern. When you evaluate each option, you should look for unnecessary or missing consonants and check whether vowels appear in the usual positions. Familiarity with similar words such as aggressive helps reinforce the correct double g and double s combination.

Step-by-Step Solution:
Step 1: Recall the standard spelling you have seen in books and newspapers: aggression.Step 2: Break the word into parts: ag + gres + sion, noting the double g and double s.Step 3: Compare option C Aggression with this pattern and see that it matches exactly.Step 4: Check option A Aggrression, which contains three r letters, so it is clearly incorrect.Step 5: Check option B Aggrresion, which has double r but only one s and therefore does not match the correct pattern.Step 6: Check option D Agrresson, which misplaces letters and also fails to use the correct ending sion.

Verification / Alternative Check:
A quick verification method is to think of the related adjective aggressive, which you may know from phrases like aggressive behaviour. Aggressive clearly has double g and double s. The noun is formed by replacing the ending ive with ion, resulting in aggression. This mental link between the adjective and the noun confirms the double consonant pattern and shows that option C is correct.

Why Other Options Are Wrong:
Aggrression adds an extra r, which does not appear in standard English spelling of the word. Aggrresion uses double r but only one s, breaking the pattern shared with aggressive. Agrresson shifts the letters into an unusual order and also uses on instead of ion, which is a common noun ending for words that describe actions or processes. These misspellings may look similar at a quick glance but are all incorrect when you analyse the letter patterns carefully.

Common Pitfalls:
Many learners confuse which consonants to double when spelling words of Latin origin. They sometimes overcompensate by adding extra letters or undercompensate by removing one of the needed doubles. A useful strategy is to connect related word families in your memory, such as aggression and aggressive, and to note identical core spellings. Reading widely and paying attention to commonly tested words builds your spelling confidence and helps you avoid traps in such questions.

Final Answer:
The correctly spelt word is Aggression.
