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

When did you call me?

When was I called by you?

The correct passive voice of the given sentence is When was I called by you?

The active voice of the sentence is When did you call me? This sentence is in the simple past tense, which is used to describe an action that happened in the past. 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 "you" and the main verb is "call." The past participle of "call" is "called." So, the passive form of the sentence is When was I called by you?

The other options are incorrect because:

• When have I called by you ? is in the present perfect tense, while the original sentence is in the simple past tense.
• When was you called by me? is grammatically incorrect. The subject of the sentence is "you," so the verb "call" must be conjugated in the third person singular form.
• When were you called by me? is also grammatically incorrect. The verb "call" must be in the past participle form, not the past tense form.
• When I called by you? is not a complete sentence. It lacks a subject.
