The correct answer is a.: specific.
This structure (this +adj) requires an adjective and the only adjective is in a., the other options are verbs or nouns and are not correct.
An adverb is an adjective + a verb. Meaning, it's a word that describes what someone/something is doing during the action.
A (whistle) & C (referee) are both nouns - person, place, or thing.
D (red) is just an adjective - describing something
B would make the most sense, it's telling you what the referee does with his whistle.
