What happens to the phone call? Which graph is correct?

A: Hello. North Seas Shipping. Can I help you?
B: Hello Could I speak to Amanada Collins, please?.
A: One moment please, I’ll just try her office. Hello. I’m afraid she’s in a meeting. Can I take a message?
B: It’s OK. I’ll try again this afternoon.

M: Could you tell us something about the economic forecasts for next year?. For example, what will happen to housing costs?
F: Well, there’s good news for buyers. Prices can’t increase. In fact, they’ll fall slightly.
M: Why?
F: There are different reasons for this. One is that it won’t be so easy to borrow money. A second reason is that there are still a lot of empty new houses on the market.
M: I see. Thank you.
