Correct Answer He did not understand and could not have understood

The correct answer is option 3 i.e. He did not understand and could not have understood.

In the given sentence, two forms of the same verb are used. If two forms of the same verb come in a sentence, both the forms will have to be separately mentioned in the sentence.
