Answer 1

Hint: Active voice and Passive voice are the two ways of expressing an action undertaken by the subject on the object of the sentence. The meaning of the sentence in active or passive voice doesn’t change except the changes in the structure of the sentence.

Complete answer:
Active voice – subject + Action (verb) + Object.
Passive voice - Object + Action (Verb) + Subject.
Option A) The DVD recorder have not been repaired – This option is not correct because The DVD recorder have not been repaired is grammatically incorrect, the use of the word “have” is not correct in the sentence. Hence, option A is incorrect.
Option B) The DVD recorder has been repaired – This option is not correct because The DVD recorder has been repaired is grammatically incorrect. Hence, option B is incorrect.
Option C) The DVD recorder had been repaired – This option is not correct because The DVD recorder has been repaired is a past perfect tense and a passive voice uses past participle form of a main verb irrespective of tense. Hence, option C is incorrect.
Option D) The DVD recorder has not been repaired – Regardless of the tense, the passive voice always uses the past participle form of the main verb. Only the auxiliary verbs are dependent on the active voice sentence.
Option D is right because the given sentence is in active voice, and in order to transform it to passive voice, the subject (The mechanic) must take the place of the object, and vice versa. 'Been' is also added since the sentence is in the present perfect tense.

The correct answer is option (D) The DVD recorder has not been repaired.

Note: "A did B" is an example of an active sentence. Passive sentences, on the other hand, take the form "B was done to A." As a result, active sentences are easier to read and are often succinct and more direct. As a result, many companies instruct their employees to avoid using passive sentences.
Many grammar checkers (whether computer programmes or real people) would suggest an active version of your passive sentence because it is so common. If you prefer the passive version, go ahead and stick with it.
