Select from following answers:

If the URL is wrong or the file does not exist,it will return isValidURL false.
If the URL is correct and the file exists at the proper URL,it will return isValidURL True.
This program checks if a file Exists at a specified URI and if so, returns the file content
The WebClient class Provides common methods for sending data to and receiving data from a resource identified by a URI.
