Is this the pair you meant? ,M: Yes, that's it. What are these trousers made of? My son's skin is quite sensitive, so I have to be careful about the material of the clothes he wears. ,F: These are made of cotton, sir. These are made by a famous children's brand called Wonder World. It's a very popular brand because of the good quality material. ,M: Oh, that's good. What other colors do these trousers come in? If you have blue, that would be great. Blue is my son's favorite color. I'd rather not have black or gray.
(A) F: Yeah, so black is your son's favorite color. (B) F: Yeah, so grey is your son's favorite color. (C) F: Okay, so your son doesn't like blue color. (D) F: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that?
