Question

Select the option that best fills in the blank and completes the sentence given below. We ________ study so much in the past.

• A. didn’t use to
• B. doesn’t used to
• C. didn’t used to
• D. doesn’t use to

Hint:

With "did", always use the base form of the verb — never add another past tense marker.

Answer 1

The Correct Option is A

“Didn’t use to” is the correct negative form of “used to”. The auxiliary “did” already puts the verb in past tense, so “used” loses the ‘d’ after “didn’t”.
