He aspires to become the more influential leader in the country representing marginalised communities.
Show answer & explanation
Correct answer: B
Explanation
Comparative Degree: Used to compare two things (e.g., "more influential"). This would only be used if he were being compared to one other person.
Superlative Degree: Used to compare one thing against a whole group (e.g., "most influential"). Since the sentence refers to his status "in the country" (a large group), the superlative degree is required.
Superlative adjectives (like most influential) almost always require the definite article "the" because they refer to a specific, unique position at the top of a category.
Correct sentence should be:
"He aspires to become the most influential leader in the country representing marginalised communities."
