Answer:
Is he has to be called by her?
Step-by-step explanation:
Active voice is when the subject acts upon the verb. In other words, active voice is when the subject is at the front of the sentence.
On the other hand, passive voice is when the subject is the receiver of the verb. This means that the subject is placed after the verb in the sentence.
The given sentence "does she have to call him?" can be changed into the passive voice as
Is he has to be called by her?
Here, the "does" in the active voice becomes nonexistent in the passive voice, being replaced by the helping verbs "is/am/are" in the new sentence.
