To change a sentence from Active Voice to Passive Voice, we need to identify the subject, verb, and object in the active sentence. Then, we transform the sentence by making the object of the active sentence the subject of the passive sentence, using the appropriate form of "to be" + past participle of the main verb, and often including "by" + the original subject.
Correct Option: A) Letters are written by them.
The question asks to identify the voice of the given sentence: "The book was written by Shakespeare." We need to determine if the subject is performing the action (active voice) or receiving the action (passive voice).
B) Passive — The sentence "The book was written by Shakespeare" is in the passive voice because the subject ("The book") is receiving the action of being written, rather than performing it. The structure (form of 'to be' + past participle + 'by' agent) is characteristic of the passive voice.
The question requires selecting the correct verb tense to complete the sentence, which describes an action that started in the past and has a connection to the present (the novel is being published now).
C) has written
The present perfect tense "has written" correctly conveys that the action of writing the novel was completed in the past, and its result (the written novel) is relevant to the present situation, i.e., its current publication. This tense establishes a clear link between the past action and the present event.
To change an active voice sentence to passive voice, we need to identify the subject, verb, and object in the active sentence.

To change an active voice interrogative sentence (question) into passive voice, we need to identify the subject, verb, and object in the active voice, then restructure the sentence. The general rule for changing 'Who' questions to passive voice is to use 'By whom' at the beginning of the passive sentence, followed by the auxiliary verb, the object of the active voice, and then the past participle form of the main verb.
A) By whom was this poem written? This option correctly applies all the rules for converting an interrogative sentence starting with 'Who' from active to passive voice in the simple past tense. 'By whom' replaces 'Who', 'was' is the correct auxiliary verb for 'this poem' in the past tense, and 'written' is the past participle of 'wrote'.
