Answer:
Which girl is the cleverest in the class
Step-by-step explanation:
The word cleverest is a superlative adjective; It's an adjective that takes a comparison to the highest degree. ... While a comparative adjective describes the difference between two items, a superlative adjective compares three or more nouns. For example: My mother's cooking is the best in the family. That girl is the cleverest in the class.
