Explanation For answer B, this paragraph from Cisco confirms it is the correct answer: “When you implement a root bridge in a switching network, you usually refer to the root bridge as the root switch. Each VLAN must have its own root bridge because each VLAN is a separate broadcast domain. The roots for the different VLANs can all reside in a single switch or in various switches.” Reference: https://www.cisco.com/c/en/us/support/docs/lan-switching/spanning-tree-protocol/5234-5.html

The answer should be B, NOT A. Explanation: (from page 80 of the book ICND2 200-105 by Wendell Odom) Command "spanning-tree vlan vlan-id root primary" or "spanning-tree vlan vlan-id root secondary" is used to set the switch as primary root switch or secondary one.
