Choose the sentence in the Active Voice:

The wind blew down the trees.

The correct answer is Option (4) → The wind blew down the trees.

In an active voice sentence, the subject performs the action. Let's analyze the provided sentences:

1. "The film was directed by Satyajit Ray." Passive voice (the film is the receiver of the action).

2. "The door was opened by the owner of the house." - Passive voice (the door is the receiver of the action).

3. "We are taught English by Mrs. Mithai." Passive voice (we are the receivers of the action).

4. "The wind blew down the trees." - Active voice (the wind is the subject performing the action).

In sentence 4, "The wind" (subject) performs the action of blowing down the trees, making it an active voice sentence.
