Select the correct passive form of the given sentence.

She told me to wait here.

I was told to wait here by her.

The correct passive form of the given sentence is I was told to wait here by her.

The active voice of the sentence is She told me to wait here. 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 "she" and the main verb is "tell." The past participle of "tell" is "told." So, the passive form of the sentence is I was told to wait here by her.

The other options are incorrect because:

• I am told to wait here by her. is in the present tense, while the original sentence is in the simple past tense.
• I was told to wait there by her. is grammatically incorrect. The adverb "there" is not necessary in the passive voice.
• I was told to wait here by her. is grammatically incorrect. The adverb "here" should be "there" because the action of telling me to wait happened in the past.
