Active voice

Explanation:

The active voice describes a sentence where the subject performs the action stated by the verb. It follows a clear subject + verb + object construct that's easy to read. In active sentences, the subject is who/what is completing the action of the verb.

The passive voice is used when we want to emphasize the action (the verb) and the object of a sentence rather than subject. This means that the subject is either less important than the action itself or that we don't know who or what the subject is.
