The correct answer is A. "Give me back that notebook," she said.
Explanation:
In narrative texts, dialogue refers to a conversation between two or more characters. This can be identified because the words of characters are enclosed in quotations (") and after this it is common to find expression such as she/he said, comment, claim, etc which makes dialogue different to quotation in formal document in which the words quoted belong to a character, article or document instead of being the words of a character. This means "Give me back that notebook," she said is a line of dialogue because it includes the word of a character that can be identified due to the use of quotations and the expression "she said".
