B and E is correct. The PAMAuthentication, PermitPlaintextLogin and UsePasswords options don't even exist in the sshd_config file

B and E is correct. PasswordAuthentication: Specifies whether password authentication is allowed. ChallengeResponseAuthentication: Specifies whether challenge-response authentication is allowed (e.g. via PAM or though authentication styles supported in login.conf(5)) https://linux.die.net/man/5/sshd_config
