Fill in the blank with the most suitable verb from the options given below:
______ he know that tomorrow you will be on leave?
The correct option is A Does
An auxiliary verb is a verb that is used along with another main verb to form tenses, negatives, and questions. Examples are: 'be', 'have' and 'do'. It usually comes before the main verb.
The auxiliary verb, 'have' is used to form perfect tenses or used with the infinitive to express an obligation (Example: I have to be there). In the given sentence, the clause, '_____ he know' is in simple present tense form and not in the perfect tense. There is no infinitive or obligation. Hence, the auxiliary verb, 'have' cannot be used. Hence, both options C and D are incorrect.
The clause, "_____ he know' is an interrogative in the simple present tense. The appropriate form of the auxiliary verb, 'do' is used in the interrogative of simple present and simple past tenses.So, the answer is either 'do' or 'does'. If the subject is in the third person singular form, the auxiliary verb, 'does' is used. Otherwise, 'do' is used. Here the subject is 'he', which is in the third person singular form. Hence, option B is the correct answer and option A is incorrect.
