The subject of the Active Voice is changed into the object of the Passive voice. Also, the object of the Active Voice is changed into the subject of the Passive Voice.
The usage of a "to be" form of verb is necessary while changing the voice of the sentence from Active to Passive.
In Passive Voice, the preposition "by" is used before the object. However, it is optional in some cases.
The question in Active voice is an interrogative sentence. The answer to this question will be either "yes" or "no".
These types of sentences usually begin with a helping verb like "Did".
The format of such a sentence in Active voice is: Did + Subject + V1 + Object?
Therefore, in Passive voice, the format will be: Was/Were + Object of the active voice (Subjective case) + V3 + by + Subject of the active voice (Objective case)?
For example:
Did he beat you? (Active)
Were you beaten by him? (Passive)
The options except (4) don't follow the correct grammatical format of the Passive Voice.
Thus, the correct answer is: "Was the noise heard by you?"
