Correct option is D
✔️ Option (d)
is not big enormous contains the error.
Explanation:
This is a case of
incorrect adjective pairing. You cannot use
two adjectives together like “
big enormous” without a conjunction or modifier in between.
Correct usage:
· “is not big enough”
· or “is not enormous enough”
Grammatical rule used: Two adjectives cannot be used in succession
without coordination or separation unless one modifies the other properly.

Hindi explanation: "Big" और "Enormous" दोनों adjectives हैं। इन्हें बिना linking word (जैसे ‘and’, ‘or’, ‘but’) के एक साथ नहीं लिखा जा सकता।
