a. I am tired.
b. I have studied all night.
c. I will sleep late tomorrow.
d. a & b
e. b&c

Answer 1

The correct answer to the question is (d) a & b, where 'am' and 'have' are the auxiliary verbs.

Step-by-step explanation:

The subject of this question is identifying auxiliary verbs within given sentences. An auxiliary verb is a verb that adds functional or grammatical meaning to the clause in which it appears, such as to express tense, aspect, modality, voice, emphasis, etc. In the sentences provided, the underlined elements 'am' in sentence (a) and 'have' in sentence (b) are auxiliary verbs.

'Am' is used as a helping verb in a progressive tense construction, and 'have' is used as a helping verb in a perfect tense construction. Therefore, the correct answer is (d) a & b. Option (c), 'will,' is also an auxiliary verb, but it is not underlined in the given sentences, so it does not meet the criteria of the question.
