Explanation

Disabling unused ports on the switch means any physical port that no authorized user is connected to is administratively shut down. An attacker who plugs into an unused port gets no network access. Assigning static IPs (A) does not prevent someone from plugging in-they can simply set their own static IP. Disabling new VLANs (B) has no effect on unauthorized physical connections. Disabling PoE (D) only cuts power delivery to PoE devices and does not restrict network access.
