When the subject of a sentence performs action is written in voice.?

When the subject of a sentence performs the action, it is written in active voice.

Here's a breakdown:

* Active voice: The subject directly performs the action.

* Example: "The dog chased the ball." (The dog is the subject and it's doing the chasing)

* Passive voice: The subject is acted upon. The action is performed by someone or something else.

* Example: "The ball was chased by the dog." (The ball is the subject, but it's not doing the chasing, the dog is)
