Select the word segment that substitutes (replaces) the bracketed word segment correctly and completes the sentence meaningfully. Select the option 'no correction required' if the sentence is correct as given.
This newly arisen (evidence could have proved) to be the final nail in the coffin for the accused.

Correct option is D

The correct substitution of the highlighted words is (d) evidence could prove.
Explanation:
· The modal verb “could” when used with the base form “prove” expresses possibility or potential in the past or hypothetical scenario.
· The phrase “could have proved” would require the sentence to refer to missed opportunity or failure, which is not indicated in this context.
· The evidence is being discussed as having potential, so “could prove” is the grammatically accurate and contextually appropriate form.
· Grammatical rule used:
· “Could + base verb” = to express possibility in general
· “Could have + past participle” = to express missed possibility or unrealized potential in past
· Example:
· Correct: This clue could prove his innocence.
· Incorrect: This clue could have proved his innocence. (unless it’s about a lost chance)
· Information booster:
· Modal verb combinations are tested frequently in substitution-type questions, especially involving could, should, and might.
