What are they going to discuss in the meeting?

【听力原文】
A: Roger? Would it be possible to meet with you to discuss my department's budget?
B: Of course, Debbie. Let me look at my schedule,
-- I have some free time on the 12th. That's this Thursday at 9:00 a.m.
A: All right. That'll be fine. Can you put together a rough idea of the kind of money I'll have available for the next year?
B: Certainly.  I've already worked out a general budget for all the departments.
推断题。开始第一句提到是谈论本部门的预算，后从“I’Il have available for the next year”可得出应该是关于明年的预算，总结起来应该是要探讨关于本部门明年的预算，故选A。
