Correct option is B
The correct substitution of the highlighted words is (b) more creative.
Explanation:
The sentence implies a comparison — to win, one must be more creative than others. The word “creative” is a polysyllabic adjective, so its comparative form is made using “more”.
Grammatical Rule Used:
For adjectives with two or more syllables (except those ending in -y), use more/most for comparison.
Example: She is more intelligent than her peers.
Information Booster:
Incorrect forms like "creativer" or "creativest" are grammatically wrong.
