T The ssh command is used to connect to a remote host using the Secure Shell (SSH) protocol, which provides encrypted and authenticated communication. The ssh command has the following syntax:

ssh [options] [user@]hostname [command]

The options can modify the behavior of the ssh command, such as specifying the port number, the identity file, the cipher, the compression, and the timeout. The user@hostname specifies the username and the hostname of the remote host to connect to. The command is an optional argument that specifies the command to execute on the remote host.

To connect to the remote host example.com which has OpenSSH listening on TCP port 2222, two possible options are:

B. ssh -p 2222 example.com: This option uses the -p flag to specify the port number of the remote host. The -p flag is a shortcut for the Port option, which can also be used with the -o flag.

C. ssh -o Port=2222 example.com: This option uses the -o flag to specify a configuration option for the ssh command. The -o flag can be followed by any option that is valid in the ssh_config file, such as Port, IdentityFile, Cipher, Compression, and ConnectTimeout. The Port option sets the port number of the remote host.

The other options in the question are not correct for this task. The --port option is not a valid option for the ssh command. The GatewayPort option is used to specify whether remote hosts are allowed to connect to local forwarded ports. The example.com:2222 syntax is not valid for the ssh command.
