Which sentence correctly demonstrates the third conditional, used for an unreal, hypothetical situation in the past?

Explanation

The third conditional uses the past perfect tense in the ‘if’ clause and ‘would have’ plus the past participle in the main clause to describe a hypothetical situation in the past that did not actually happen, as in ‘If I had studied harder, I would have passed the exam.’ This structure is specifically used for imagining a different outcome to something that has already occurred and cannot be changed.
