Why each option

The standard and default port for SSH (Secure Shell) is port 22.

A80

Port 80 is the standard port for HTTP (Hypertext Transfer Protocol), not SSH.

B53

Port 53 is the standard port for DNS (Domain Name System) services, not SSH.

C22Correct

SSH, or Secure Shell, is a cryptographic network protocol for operating network services securely over an unsecured network, and its well-known port number is 22, which is the port typically allowed for SSH traffic in security policies.

D23

Port 23 is the standard port for Telnet, which is an insecure protocol, not SSH.
