In the following question, the sentence given with a blank is to be filled in with an appropriate word. Select the correct alternative out of the four and indicate it by selecting the appropriate option.
It does not suit you to cast ______ on the character of such a pure woman.

The correct option is D.
Cast aspersions is a well-known idiomatic phrase which means to make critical, attack, or damaging remarks about someone's character or reputation.

Praise means to express warm approval or admiration, which contradicts the negative intent indicated by "such a pure woman" (implying the action is inappropriate or insulting).

Abuses and vituperations mean cruel remarks or language, but they do not collocate with the verb "cast" in standard English idioms.
