B. mv .ssh/authorized_key .ssh/authorized_keys This changes the name of the file from authorized_key to authorized_keys, which is the conventional name for the file that contains authorized public keys for passwordless SSH connections. By convention, the ssh-keygen tool generates the authorized_keys file, and some SSH servers expect this exact name. Changing the name of the file to authorized_keys may resolve the issue and allow the passwordless connection to be established.
