The correct answer is: B. He exclaimed that it was a cold day.
The word “exclaimed” means to say something suddenly and loudly, often with surprise or emotion. In this case, the man is surprised by the cold weather and expresses his surprise by exclaiming “What a cold day!”
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option A is incorrect because the man is not simply telling the woman that it is a cold day, he is exclaiming it. Option C is incorrect because the man is not expressing sorrow, he is expressing surprise. Option D is incorrect because the man does not say that it is a very cold day, he simply says that it is a cold day.
In conclusion, the correct answer is: B. He exclaimed that it was a cold day.
