The description that best defines active voice is option number 2, which states "please use in writing which subject of a sentence does the action." Active voice is a grammatical construction in which the subject of a sentence performs the action described by the verb. In active voice, the subject is the doer of the action, and it is typically positioned at the beginning of the sentence. Using active voice in writing helps to create more concise and direct sentences. To determine whether a sentence is in active voice, you can ask yourself, "Who or what is performing the action?" If the subject is responsible for carrying out the action, then the sentence is in active voice.
