Correct Answer: The coffee will be brought by the boy.

Solution : The correct choice is the first option, " The coffee will be brought by the boy ."

Explanation: To change it to the passive voice, we need to use the appropriate form of the verb "bring" in the passive construction. In this case, it becomes "The coffee will be brought by the boy." The subject of the active voice becomes the agent in the passive voice, and the object of the active voice becomes the subject in the passive voice. The passive structure to be followed in the case of the simple future tense is: "Object + will be + past participle form of the main verb + by followed by the agent of the action.

So, the correct sentence would be: "The coffee will be brought by the boy."
