The correct answer is A. Conditional
Step-by-step explanation:
In this sentence, the verb "run" and other grammatical elements are used to show one action "run the fastest" will lead to a consequence or effect "win a trophy". This is known as the conditional mood as the occurrence of one event is conditioned by another. Moreover, it is possible to know this verb and all the sentences belong to the conditional mood because this begins with the word "if" that introduces the conditional. Moreover, this sentence does not express a fact (indicative mood), a question (interrogative mood), or an order (imperative mood.)
