The correct answer is: B. He asked us to let him have some tea.
The sentence “He said, ‘Let me have some tea'” is an example of a direct command. The speaker is directly asking the listener to do something, in this case, to let him have some tea.
Option A is incorrect because it does not accurately reflect the meaning of the sentence. The speaker is not telling someone else to let him have some tea, he is asking them to do so.
Option C is incorrect because it does not accurately reflect the mood of the sentence. The speaker is not expressing a wish, he is making a request.
Option D is incorrect because it does not accurately reflect the tense of the sentence. The speaker is not talking about something that will happen in the future, he is talking about something that he wants to happen right now.
