Correct Answer: Superman was created by Marvel Comics.

Solution : The first option is correct.

The passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active sentence becomes the subject in the passive voice.

The structure of the passive sentence as per the simple past tense is: " Singular subject + was + past participle form of the verb + by followed by the agent of the action."

Therefore, the passive statement would be, "Superman was created by Marvel Comics".
