Question

Which would be an appropriate follow-up question to ask this student?

Answer 1

Answer:

The appropriate follow-up question to ask this student, according to the text you added in the comment box, would be the second one: "What are the health problems caused by sugary drinks?"

The other questions would also be accurate if the conversation continues, but, as a follow-up question to this student's comment, the second one would be the one because it is directly related to his statement and digs deeper into the subject he is talking about.
