  2. Fast mode ports
  3. Root bridge
  4. BDPU priority
Explanation
Answer - C - Before the STP can converge into a switched LAN, you must elect the root bridge.

Key Takeaway: The root switch in an STP is the logical center of the spanning-tree topology in a switched network. All paths that do not need to reach the root switch are placed in the backup mode.
