Agree on C as the answer: “ If the bridge receives superior STP bridge protocol data units (BPDUs) on a root-protected interface, that interface transitions to a root-prevented STP state (inconsistency state) and the interface is blocked.” from https://www.juniper.net/documentation/us/en/software/junos/stp-l2/topics/ref/statement/no-root-port-edit-protocols-stp.html
