Explanation

'dot1x pae authenticator' (A) is the interface-level command that configures a switch port as an 802.1X authenticator (PAE = Port Access Entity), enabling 802.1X authentication on that specific interface. 'dot1x system-auth-control' (B) is a global-level command, not interface-level. 'authentication host-mode single-host' (C) configures how many hosts are allowed per port but does not enable 802.1X. 'aaa server radius dynamic-author' (D) configures Change of Authorization (CoA), unrelated to enabling 802.1X per interface.
