Select the option that expresses the given sentence in passive voice. Meenakshi could have sent a reply.
- (a)A reply could have been send by Meenakshi.
- (b)A reply could have be sent by Meenakshi.
- (c)A reply could have been sent by Meenakshi.
- (d)A reply could have sent by Meenakshi.
Answer
Why
Correct — C. The active verb is could have sent — a modal (could) sitting on a perfect (have + past participle).
Two pieces never move. After a modal the next word stays the bare have, and the passive of a perfect is have been + past participle.
could have sent → could have been sent
The object, a reply, moves to the front and the doer follows as by Meenakshi.
That is option (c).
Why the others are wrong
- (a)A reply could have been send by Meenakshi. — Every link of the chain is right except the last: send is the base form, and a passive needs the past participle sent (send - sent - sent). This is the option most people lose the mark to.
- (b)A reply could have be sent by Meenakshi. — After have the verb must be the participle been, not the bare infinitive be. 'could have be sent' is not a possible English verb chain.
- (d)A reply could have sent by Meenakshi. — It drops been altogether, so the chain stays active in form. As written it says the reply did the sending.
Concept
Turning an active sentence passive is one swap and one rebuild. The object moves to the front, the doer goes into a by-phrase, and the verb becomes be + past participle in the tense the original used.
A modal perfect is where candidates slip. Nothing after a modal is ever conjugated, so could have carries across untouched and only the lexical verb changes.
Active: could have + sent
Passive: could have + been + sent
The same shape gives should have been, must have been and might have been.
All four options open 'A reply could have' and close 'by Meenakshi.' The entire question lives in the two or three words between, so read only the verb chain and ignore the rest.
Key facts
- The passive of a modal perfect is modal + have been + past participle, as in could have been sent.
- Send is an irregular verb whose past tense and past participle are both sent.
- After a modal (could, should, must, might) the next verb is a bare infinitive - have, never has or had.
- The object of the active sentence becomes the subject of the passive one.

Common traps
- Writing could have been send, using the base form where the participle belongs.
- Dropping been, which leaves a chain that is still active in shape.
- Swapping could for would or can, changing the modal the sentence actually gave you.
