It is the first one.

Answer:

a debate between students about a topic from history

Explanation:

Conversations of Mothers about grades are hardly formal talk, same goes to weekend plans. Chatting already implies that this is not a formal conversation.

This all is quite different than two students discussing about a period in history, a historical character, or something similar. In this case, the discussion is academic and most likely to be formal than the other situations.
