Answer is Wrong!
Answer is Right!
The correct answer is D. fanciful.
Frivolous means not serious or important. Momentous means very important or significant. Frantic means very excited or worried. Serious means important or requiring careful thought.
In the sentence “His frivolous remarks provoked no comments,” the
speaker is saying that the person’s remarks were not serious or important, and therefore did not warrant any response.
