Choose the correct synonym of Exasperate.
Explanation
In this vocabulary item, Irritate is the closest synonym of Exasperate, so option C is correct. The word Exasperate and the word Irritate share the same central sense in the context tested by the question, although usage, tone and grammatical form should still be checked before substituting one for the other. A synonym is not required to be identical in every possible sentence; it must preserve the intended meaning in the relevant context. Here, replacing Exasperate with Irritate keeps the core idea intact without reversing the tone or changing the action, quality or state expressed by the target word. The alternatives Faultless, Confuse and Pollute do not express the same central meaning as Exasperate. This distinction matters because competitive examinations often place one accurate synonym beside three familiar but contextually unsuitable words. To verify Exasperate independently, identify its part of speech, state a short definition, and place both Exasperate and Irritate in the same simple sentence. If the sentence retains its essential meaning and grammatical structure, the synonym relationship is supported. Learners should revise Exasperate together with Irritate, a brief usage cue and the contrasting distractors.
