Select the correct direct form of the given sentence.

She asked me why I had been smoking that day.

She said to me, "Why were you smoking today?"

The correct direct form of the given sentence is:

She said to me, "Why were you smoking today?"

The other options are incorrect for the following reasons:

• She said to me, "Why are you smoking today?" - The past continuous tense is not appropriate in this context, as the speaker is asking about the other person's smoking habit in general.
• She said to me, "Why you smoke today?" - The sentence is grammatically incorrect.
• She says to me, "Why were you smoking this day?" - The present tense verb "says" is not appropriate in this context, as the speaker is reporting what the other person said to them in the past.
