A network administrator runs 'show spanning-tree' and sees that a core switch has bridge priority 32768 and a distribution switch has bridge priority 24576. Which switch is the STP root bridge, and what does the lower priority value mean?

• A.Neither switch is the root bridge; the switch with the lowest MAC address is always elected root regardless of priority
• B.The core switch is the root bridge because the higher priority value (32768) indicates it was manually configured as the primary root
• C.The distribution switch is the root bridge because it has the lower bridge priority value - lower bridge priority wins the root election; 24576 < 32768
• D.Both switches are root bridges on their respective spanning tree instances because they have different priority values
