In the sentence below, there is one underlined word and one gap. From the list of words lettered A to D, choose the one that is most nearly opposite in meaning to the underlined word and that will, at the same time correctly fill the gap in the sentence.

I can vouch that he broke the glass accidentally and not .....

Answer Details

The word that is most nearly opposite in meaning to "accidentally" is "deliberately". "Accidentally" means that something happened by chance or without intent, while "deliberately" means that something was done on purpose or intentionally. In this context, the speaker is saying that they can vouch that the person broke the glass accidentally and not intentionally or deliberately. Therefore, the correct word to fill the gap is "deliberately".
