Example Input: M: Diana, can you give me a hand? I'm supposed to place all these new products in the display case, but they'll never fit. ,F: Yeah, I see what you mean. But did Miss Harper mean to put them all on display, or just one of each as a sample for the customers to see? ,M: Oh, I get it! So maybe I should just select a single example of each model instead of one of each color for each model. ,F: Check with Miss Harper first. But in my opinion, that's the only way you'll be able to do it.
(A) M: I manage to put them all in the case, but I can't find Ms.Harper to check. (B) M: It's all because of the limited space. Daisy, throw away these products. (C) M: Well, it's all because there isn't enough room for all the new products. (D) M: I'm sorry, I didn't catch that. Would you mind speaking more slowly?
Example Output: C
