The word Contradict and the word Deny 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 Contradict with Deny keeps the core idea intact without reversing the tone or changing the action, quality or state expressed by the target word. The alternatives Favorable, Scatter and Attention do not express the same central meaning as Contradict. This distinction matters because competitive examinations often place one accurate synonym beside three familiar but contextually unsuitable words. If the sentence retains its essential meaning and grammatical structure, the synonym relationship is supported. Learners should revise Contradict together with Deny, a brief usage cue and the contrasting distractors.
