Which sentence correctly defines verb voice?

A. Verb voice indicates whose voice is speaking in a sentence.

B. Verb voice indicates whether someone is speaking in a sentence.

C. Verb voice indicates how loudly or softly to read a sentence.

D. Verb voice indicates the relationship between a verb and its subject and object.

In grammar, the voice of a verb describes the relationship between the action (or state) that the verb expresses and the participants identified by its arguments (subject, object, etc.). When the subject is the agent or doer of the action, the verb is in the active voice. When the subject is the patient, target or undergoer of the action, the verb is said to be in the passive voice. Voice is sometimes called diathesis.[1]

The following pair of examples illustrates the contrast between active and passive voice in English. In sentence (1), the verb "ate" is in the active voice, but in sentence (2), the verbal phrase "was eaten" is in the passive voice. Independent of voice, "the cat" is the Agent (the doer) of the action of eating in both sentences.

(1) The cat ate the mouse.

(2) The mouse was eaten by the cat.

In a transformation from an active-voice clause to an equivalent passive-voice construction, the subject and the direct object switch grammatical roles. The direct object gets promoted to subject, and the subject demoted to an (optional) adjunct. In the first example above, the mouse serves as the direct object in the active-voice version, but becomes the subject in the passive version. The subject of the active-voice version, the cat, becomes part of a prepositional phrase in the passive version of the sentence, and can be left out entirely

Verbs in English have voice, which refers to the relationship between the subject of the sentence and the verb.

Examples of Verb Voice:

There are two verb voices in English:

Active Voice-when the subject of the sentence the person or thing doing the action of the verb or in the state expressed by the verb. This is the voice with which we are most familiar-the subject performs the action of the sentence.

Passive Voice-when the subject of the sentence is being acted upon. The subject of the sentence is not performing the action. Instead, it is receiving the action.

Most writers do not use passive voice. Passive voice should only be used when you need to emphasize the thing that is being acted upon.

to write a sentence in the passive voice, you must use an auxiliary verb, or "helping" verb.

Examples of sentences written in active voice:

1) Joseph threw the ball through the neighbor's window.

2) Alyssa drank the last bottle of water.
