Why doesn’t the man carry a camera with him?

Listen to the conversation， mark each question as A， B， C or D according to what you hear.
M: Did you take these pictures? They’re very good.
W: Yes， I think they turned out well too. I like to take my camera with me wherever I go. That way， if I see something interesting， I can snap a picture of it.
M: Carrying a big camera around is too much trouble for me.
W: My camera is really small though. Here let me show you.
M: That is a compact camera， but you really must know a lot about photography to get such professional looking results.
W: Not necessarily. This camera is simple to operate.
M: Does this model come with a flash attachment for indoor shots?
W: Better than that. It has a built-in electronic flash and automatic focus， too. I don’t even have to worry about focusing.
M: That’s what I need. When I take pictures they usually come out blurry because I don’t adjust the lenses properly and I hate photos that are out of focus. Is a camera like yours expensive?
W: Less than you’d expected. Why don’t you check the prices at Hatfield’s down the street? This model was on sale there last week.
M: I think I will. It certainly won’t hurt to take a look.
