A. Server
B. Client
C. Peer
D. Sender

Solution

C. Peer

Explanation

In a peer-to-peer (P2P) network, each computer is commonly referred to as a "peer." In a P2P network, there is no centralized server or hierarchy among the computers. Instead, each computer (or peer) has equal status and can act as both a client and a server, sharing resources directly with other peers on the network.
