Explanation:
The conditional mood is a grammatical mood used to express a proposition that is subject to a particular condition in order to happen. This sentence contains a conditional type 3, also called the third conditional, which is a structure used to talk about unreal situations in the past, situations that did not happen. It consists of two clauses: An if clause and a main clause. The former contains the past perfect form of the verb (auxiliary verb had + past participle) and the main clause contains a modal verb (would, could, or might), the auxiliary verb have plus the past participle form of the verb.
