Answer 1

Hint: Active voice means that a sentence has a subject that acts upon its verb. Passive voice means that a subject is a recipient of a verb's action.
Active voice : Subject+ will+ first form of verb+ object
Passive voice : Subject+ will+ first form of verb+ object

Complete answer:
A sentence with an active voice has a subject who acts on the verb. A subject is a beneficiary of a verb's action in a passive voice.

Now let us look into the given options:
Option A) The office would be cleaned by somebody: It is incorrect because it has not omitted the subject ‘somebody’.
Option B) The office will be cleaned tomorrow: It is the correct option because the subject of the given sentence is 'somebody,' who performs the action 'will clean.' When the subject pronouns used are indefinite, such as somebody, nobody, anybody, they, and so on, the subject is omitted in the passive voice. As a result, the subject 'somebody' is omitted when the given sentence is changed to passive, and the response is: The office will be cleaned tomorrow.
Option C) Somebody will be cleaning the office tomorrow: It is incorrect because the voice has not been transformed to passive. Just the tenses have been changed.
Option D) None of the above: It is incorrect because Option B. is the correct option.

Thus the correct answer is option ‘B’.

Note: We claim a sentence is in the active voice when the subject of the sentence performs the verb's action. The active voice uses a loud, direct, and consistent tone in its sentences. When the verb acts on the subject, the sentence is said to be in the passive voice. The passive voice is often made up of a conjugated form of to be and the past participle of the verb.
