单选题

A Dead animals found in dustbins.

B Small animals stolen from houses.

C Food given to them by people.

D Food that hunted by themselves.

解析：
对话中女士提到现在许多人经常看到城镇的狐狸(town foxes)以垃圾箱里的食物为食，男士说到那是一个谬见(that’s a myth)，他很少看到狐狸从垃圾桶拿食物吃，而且还提到“The bulk of food they get is food deliberately put out for them by householders.”(它们得到的大部分的食物是住户故意放在外面给它们的)，故答案选C。
