Input: F: Jack, our teacher let me ask you which circus tickets you've decided to buy. ,M: Well, there wasn't much choice of them. There weren't enough of the 12 pounds 50 seats for all of us, which is what I was planning to buy. And although there were lots of seats at 15 pounds 50, these were only on weekday afternoons, which I know wasn't suitable for us. So I'm afraid I've gone for the ones at 17 pounds 50. I know it's more than we wanted to pay. But at least we won't be right the back.
(A) F: That's okay, it's not your fault that they don't have enough 12.50 pounds tickets, just choose the 17.50 pounds ones. (B) F: That's alright,  I don't think it's not your fault that they don't have enough 12.50 pounds tickets, just as you said, buy the 15.50 pounds tickets. (C) F: Yeah, you're right, the time for those 12.50 pounds tickets is not suitable for us, just as you said, buy the 15.50 pounds tickets. (D) F: I am afraid I did not quite catch what you were saying. Please repeat it.
