Out of the four alternatives, choose the one that best expresses the given sentence in the passive Voice.

'Mohan will have won the match'.

The match will have been won by Mohan.

The sentence that best expresses "Mohan will have won the match" in the passive voice is: The match will have been won by Mohan.

Here's why the other options are not suitable:

• The match would have been won by Mohan: This uses the conditional past continuous passive voice, which is not the case. The original sentence expresses a future possibility, not a hypothetical scenario.
• The match was won by Mohan: This uses the past passive voice, which implies the match has already been won, contradicting the future tense conveyed in the original sentence.
• The match will be won by Mohan: This uses the simple future passive voice, which doesn't capture the additional layer of "future perfect" tense implied in the original sentence with "will have won."

Therefore, "The match will have been won by Mohan" accurately reflects the original sentence with its future perfect tense and passive voice construction. It signifies that at a future point in time, the match will be in a finished state where Mohan has emerged as the winner.
