Question

The sentence has been given in the Active/Passive voice. From the given options, choose the one which best expresses the given sentence in the Passive/Active voice.

One should keep one's promise.

• A. One's promise should be kept by us.
• B. One's promise has to be kept.
• C. A promise should be keeping.
• D. A promise should be kept.

Answer 1

The correct option is D A promise should be kept.

An action in a sentence can be represented in two ways , namely active and passive voice.

The passive voice always uses the past participle form of verb as the main verb irrespective of any tense. Only the auxiliary verbs depend upon the sentence given in active voice.

The correct answer is D) A promise should be kept.

Option D) is correct as the subject of the given sentence becomes the object and vice versa . Also, the main verb (keep) is used in the third form (kept).

Option A, B, and C are not correct as 'us' isn't needed,'has to' cannot be used and 'keeping' is not past participle form of the main verb respectively.
