In the following exhibit, you are running RSTP. Which switch interfaces will become root ports?

A. Switch A Gi0/0, Switch A Gi0/3
B. Switch B Gi0/4, Switch C Gi0/6
C. Switch B Gi0/4, Switch C Gi0/6, Switch D Gi0/8
D. Switch B Gi0/4, Switch C Gi0/6, Switch D Gi0/10

C. All three switches will have a root port leading back to the root bridge since Switch A is the root bridge. The total path cost is lower for Switch D Gi0/8 than it is for Switch D Fa0/10.
