Its A and C. 21 is FTP and 23 is Telnet, both send data unencrypted. I think some might pick B (SSH) but that's actually needed for secure admin access.
Probably A and C. FTP and Telnet both use plain text so they should be closed first for security. Makes sense, right?
Option A and C. Both FTP (21) and Telnet (23) are insecure by default, so best to close them.
