If this thing had happened (If + past perfect) that thing would have happened (perfect conditional or perfect continuous conditional).

First type of conditional sentence is used when we talk about the possibilities in the present or the future. The structure of the sentence is: If + simple present, subject + will/shall + base verb. Only option (3) fulfills this criteria.

In a future conditional construction, the main clause states a prediction depending on whether the action happens first. The simple present tense is used in the if clause, and a modal (will, can, may, might, shall) is used in the main clause.
