Examples include web servers, email servers, web conferencing servers, and streaming media servers. The load balancer is placed in front of the server network and distributes requests from the client network or Internet to the application servers. The service address is advertised to clients as a virtual server. This is used to provision high availability services that can scale from light to heavy loads. so the answer is C guys
