They are 2 similar questions use walk() and list() methods.We use list() in this one and thats why answer is C.The main difference between walk() and list is that list(dir) gives a stream of files in the directory dir , while walk() method walk the subtree of its argument including the root of subtree—the directory itself.I hope this is useful.
