“What a terrible storm it is!” he said.

He exclaimed that it was a terrible storm.
He exclaimed that it has been a terrible storm.
He exclaimed that it will be a terrible storm.
He exclaimed that it is a terrible storm.

The correct answer is D. He exclaimed that it is a terrible storm.

The sentence “What a terrible storm it is!” is an exclamation. An exclamation is a sentence that expresses strong feeling. In this case, the speaker is expressing their surprise or dismay at the severity of the storm.

The other options are incorrect because they do not accurately reflect the speaker’s feelings. Option A, “He exclaimed that it was a terrible storm,” is too passive. The speaker is not simply stating that the storm was terrible; they are expressing their strong feelings about it. Option B, “He exclaimed that it has been a terrible storm,” is also too passive. The speaker is not simply stating that the storm has been terrible; they are expressing their strong feelings about it in the present moment. Option C, “He exclaimed that it will be a terrible storm,” is incorrect because the speaker is not expressing their feelings about a future event; they are expressing their feelings about a current event.
