Answer 1

Hint:Tense is a category in grammar that expresses time reference. Tenses, particularly in their conjugation patterns, are typically manifested by the use of particular forms of verbs. Past, current , and future are the major tenses used in many languages.
Definition of perfect tense in the present. The ideal present is used to suggest an association between the present and the past. Before now, but not defined, the time of the action is and we are sometimes more interested in the outcome than in the action itself.

Complete answer:
It uses Present Perfect Tense to refer to:
A finished action and an indefinite / unspecified period in the move To an incident that started in the past and proceeded to the present moment Here, we see in the query that the speaker says that David has done his homework and can therefore go to bed.
The speaker therefore refers to an action that is completed at the time of the speech (i.e. completion of the homework), but there is no reference to time. Hence, Present Perfect is the right tense to use here.
Formulation of Present Perfect Tense sentences: have / has + past verb participle form.
"have" is used with : I / you / we / they
"has" is used with : he / she / it
Here the verb is finish, & past participle of finish is - finished.
Therefore to construct this sentence in Present Perfect Tense we will add "has" + "finished". Thus, the correct complete sentence is: David can go to bed now. He HAS FINISHED his homework.

Hence the correct answer is option ‘B’

Note: We use the present perfect simple with action verbs to emphasise the completion of an event in the recent past. We use the present perfect continuous to talk about ongoing events or activities which started at a time in the past and are still continuing up until now.
