Hint: A verb is a content word that denotes an action, occurrence, or state of existence. Verb is the word class that serves as the predicate of a sentence. For example – bend, cry.

Complete answer:In the given question, we have to find out which of the options given to us is in simple present tense, as the usage of ‘have’ in the first tense indicates that the second sentence also is in present tense.
Let us thus analyze the options given to us in this question:
(a)'needn’t', refers to simple present tense.Therefore, option (a)is correct.
(b)‘didn’t use to', refers to past tense.Therefore, option (b) is incorrect as it is not the correct tense.
(c)‘mustn’t', refers to not doing something forbidden.Therefore, option (c) is incorrect as it is not relevant to context.
(d)‘didn’t need to', refers to simple past tense.Therefore, option (d) is incorrect as we need simple present tense.

Note: In this question, it will be helpful for the student to recall the concept of tense. Tense is a grammatical category of verbs used to express distinctions of time. There are three tenses - past, present, and future.
