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