Pick out the correct sentence in indirect narration of the following sentence:
She said to him, "Please wait here till I return"

Since the quoted sentence includes the use of 'please', we deduce that it must be a request. 'She said to him' becomes 'She requested him'. Also, since the request itself is written in the present simple tense ('Please wait here til I return'), the sentence, in indirect speech, will be in the past simple. The noun 'here' will be 'there' in the indirect speech. The sentence in the indirect speech will be: She requested him to wait there till she returned. Option B is correct.
