Asked by GIANSH GUPTA KHUNDKER · BIRLA BRAINIACS
Answer: C. fastest
Answer: (C) fastest
Explanation: When comparing more than two actions (in this case, all the student athletes), the superlative form of the adverb must be used. The adverb "fast" forms its superlative by adding "-est" (fast, faster, fastest). Note that "fastly" is grammatically incorrect in English.
