Question

Select a suitable modal auxiliary to fill in the blank:

I ............ go to the wedding as I was occupied elsewhere.

• A. won't
• B. can't
• C. couldn't
• D. wouldn't

Answer 1

Answer: (C)

The correct answer is Option C.

COULDN'T is the negation of COULD.

COULD is the past tense of CAN.

CAN means the ability to do something.

In the given sentence, the speaker was not able to go to the wedding because he was occupied elsewhere.

The sentence is in the past tense, thus COULDN'T will be the correct answer.

The remaining options are incorrect because:

CAN'T is the present tense.

WON'T is the contraction of WILL NOT.

WOULDN'T expresses the desire to not do something.
