Question

Fill in the blank with the most appropriate option.

That painting ____ have been painted by Picasso. It could be a forgery.

• A. Should not
• B. Must not
• C. Might not
• D. Would

Answer 1

The correct option is C Might not

Modal Verbs show us the attitude of the speaker to what is being said or done. The term "modal" means expressing mood and mood is a way to express the attitude of the speaker.

option C is the correct answer because it expresses the mood of lesser possibility, which suits the sentence as it requires a mood of uncertainty.

Whereas option A gives an expression of going against duty or correctness; option B gives an expression of not going against supposedly; and option D expresses will to do the act in future.
