Select the synonym of Impulsive.
Explanation
In this vocabulary item, Hasty is the closest synonym of Impulsive, so option C is correct. The word Impulsive and the word Hasty 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 Impulsive with Hasty keeps the core idea intact without reversing the tone or changing the action, quality or state expressed by the target word. The alternatives Postpone, Utilize and Increase do not express the same central meaning as Impulsive. This distinction matters because competitive examinations often place one accurate synonym beside three familiar but contextually unsuitable words. To verify Impulsive independently, identify its part of speech, state a short definition, and place both Impulsive and Hasty in the same simple sentence. If the sentence retains its essential meaning and grammatical structure, the synonym relationship is supported. Learners should revise Impulsive together with Hasty, a brief usage cue and the contrasting distractors.
