Change the following sentence into Active voice.

He was appointed Chairman.

They appointed him chairman

The correct answer is Option (1) - They appointed him chairman

Reasoning:
The given sentence "He was appointed Chairman" is in the passive voice, where the subject He receives the action.

To change it into active voice, we make the doer of the action the subject:
→ They appointed him chairman.

Here, “They” (the doer) becomes the subject, “appointed” is the verb, and “him” is the object.
