Question

A) don't have to
B) mustn't
C) mightn't
D) couldn't

Answer 1

I think the option d

Answer 2

The answer is You A) don't have to come with us if you don't want to. As the word ‘to’ is added here it goes well with the finite verb come and makes a meaningful instructional sentence that is good to read. The whole sentence is written in present sentence.

With the other options the consistency of the sentence would have been hampered.
