Explanation

FlexLink is a Cisco feature that configures a pair of Layer 2 interfaces as mutual backup links. When FlexLink is enabled on a port, STP is explicitly disabled on that port because FlexLink provides its own loop-prevention and redundancy mechanism - making STP unnecessary and incompatible with its operation. PortFast (C) speeds up STP convergence by skipping listening/learning states, but STP still runs on those ports. EtherChannel (A) bundles physical links but still participates in STP as a logical port. P2p Edge (B) is an STP port type designation, not a feature that disables STP.
