From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.

if I _____ what actually happened, I would have punished him.

Answer Details

The correct answer is "had heard." This is because the sentence is in the past unreal conditional form, indicating a hypothetical situation in the past. The speaker did not hear what actually happened, but is imagining what would have happened if they had heard. The correct verb form to use in this situation is "had heard," which is the past perfect form.
