Which room did the man take finally? Which is the correct graph?

M: Is No. 2 meeting room available this afternoon?
F: Let me see... Mm... No, the Production Department will have a discussion at 2:30.
M: Then what about No. 5 meeting room? How big is it?
F: It can only hold 15 people.
M: Oh, that’s a bit too small. We have about 30 people.
F: I think No. 3 meeting room will be available at 3 this afternoon. Is that OK?
M: No problem. Thank you.

F: In general, this year’s sales situation is not as good as expected compared with last year’s. Our sales leveled off at 25,000 units during the first half of the year and then rose steadily for some time. However, it suddenly dropped to 20,000 units at the last three months of the year because of decreasing demand in the market.
