For this question, choose the option opposite in meaning to the word or phrase in bold:
It is Iudicrous to suggest that she was a government agent.
Answer Details
The opposite in meaning to "ludicrous" is "sensible".
When something is ludicrous, it means it is ridiculous, absurd or unbelievable. So, in this case, the statement "It is ludicrous to suggest that she was a government agent" means that the suggestion is ridiculous or absurd.
Therefore, the opposite of ludicrous is sensible, which means logical, reasonable, or practical. If the statement were "It is sensible to suggest that she was a government agent," it would mean that the suggestion is reasonable or practical.
