Answer :
Answer:
D. shouldn’t
Explanation:
Mrs. Campbell shouldn't change the passwords. The negative form of the auxiliary should is should not. The contracted form is shouldn't. The not is signalled by joining the n to the verb addind an apostrophe to indicate that a vowel has been ellided -o- and the t at the end. The contraction is used in oral language.
It is D. The ' also known as an apostrophe indicates the omission of letters or numbers. The apostrophe always goes where the letter is removed in contradictions, like shouldn't.
