Select the option that expresses the given sentence in passive voice.

Mandeep has repaired the truck.

The truck has been repaired by Mandeep.

The correct passive voice form of the given sentence "Mandeep has repaired the truck" is The truck has been repaired by Mandeep.

The active voice of the sentence is "Mandeep has repaired the truck." This sentence is in the present perfect tense, which is used to describe an action that has happened in the past and is still relevant to the present. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "Mandeep" and the main verb is "repair." The past participle of "repair" is "repaired." So, the passive form of the sentence is "The truck has been repaired by Mandeep."

The other options are incorrect because:

• The truck have been repaired by Mandeep." This sentence is in the present perfect tense, but the verb is plural. The subject of the sentence is singular, so the verb should also be singular.
• The truck had been repaired by Mandeep." This sentence is in the past perfect tense, which is used to describe an action that happened in the past before another action happened. However, there is no other action mentioned in the sentence.
• The truck is been repaired by Mandeep." This sentence is in the present progressive tense, which is used to describe an action that is happening now but is not finished. However, the action of repairing the truck has already been completed.
