Select the correct passive form of the given sentence.
Who has taken away my pen?

Correct option is A

· Active Voice- Active voice is a grammatical structure in which the subject of the sentence performs the action expressed by the verb.
· Passive Voice- Passive voice refers to a grammatical construction where the subject of a sentence undergoes an action rather than performing it. In passive voice sentences, the emphasis is on the recipient or object of the action.
· By whom has my pen been taken away?
This option correctly transforms the active voice question into its passive voice counterpart, maintaining the present perfect tense.
· The given sentence is present perfect tense.
· Conversion rule: By whom + auxiliary verb (has, have)+ Object + been + past participle? -> <- Who+ (has, have) + Subject + V3 + object?
