The correct answer is A. What do you like best about my introduction?
Step-by-step explanation:
An open-ended question is a type of question that usually begins with the "wh-" question words what, where, who, how, when or why and are answered by providing details rather than short answers. This type of questions are the opposite to close-ended questions that can be answered with a yes or no and that begins with an auxiliary verb such as "do" or "has". Additional to this, open-ended questions are preferred during interviews as these allow the interviewer to know the opinion and perspective of the interviewed. Considering this, the question that would be an open-ended question for you aks after someone has read your paper is "What do you like best about my introduction?", because this is the only question that requires a complex answer and not only a yes/no answer, this question begins with a wh-question word "what" and therefore is an open question that allows you to know the opinion people has about your paper.
