The correct answer is passive voice. In the sentence "The proposal was written by the consultant," the subject of the sentence (the proposal) is acted upon by the agent (the consultant). This construction emphasizes the action being done to the subject rather than who is performing the action.

In contrast, active voice would structure the sentence so that the subject performs the action, such as "The consultant wrote the proposal." The indicative mood, which expresses statements of fact or asks questions, is not applicable here as the focus of the sentence is on the action rather than its mood. Similarly, the imperative mood issues commands or requests, which is not relevant to the sentence in question, as it is not directing anyone to take action.
