Which type of voice indicates that the subject performs the action?

The correct answer is that the active voice indicates that the subject performs the action. In sentences written in active voice, the subject is the doer of the action, making the sentence clear and direct. For example, in the sentence "The cat chased the mouse," "the cat" is the subject actively doing the action of chasing. This straightforward structure enhances clarity and engagement in writing, allowing readers to easily understand who is responsible for the action.

By contrast, passive voice reverses this structure, focusing on the action itself or the recipient of the action rather than the subject. Sentences in passive voice often use a form of "to be" combined with the past participle of the main verb, such as "The mouse was chased by the cat." This can obscure who is performing the action and may lead to vagueness. Other voices, such as neutral or impersonal, do not directly relate to the subject performing the action and often lack clarity or personal engagement. Hence, the active voice is the preferred choice when you wish to emphasize the subject's role in taking action.
