Select the option that expresses the given sentence in passive voice.

The people will make him the leader.

He will be made the leader by the people.

The correct passive form of the given sentence is: He will be made the leader by the people.

The active voice of the sentence is The people will make him the leader. This sentence is in the simple future tense, which is used to describe an action that will happen in the future. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the future participle of the main verb. In this case, the subject of the active sentence is "he" and the main verb is "make." The future participle of "make" is "to be made." So, the passive form of the sentence is He will be made the leader by the people.

The other options are incorrect because:

• He had been made the leader by people. is in the past perfect tense, while the original sentence is in the simple future tense.
• He was made leader by the people. is in the simple past tense, while the original sentence is in the simple future tense.
• People made him the leader. is in the active voice, while the question is asking for the passive voice.
