Correct Answer: The light show was enjoyed by all of us.

Solution : The correct choice is the fourth option.

Explanation: 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 a passive sentence in case of the simple past tense is: " Object + was + past participle + by followed by the agent of action"

Therefore, the passive form would be: "The light show was enjoyed by all of us."
