Refer to the exhibit.

All switches have default bridge priorities, and originate BPDUs with MAC addresses as indicated.
The numbers shown are STP link metrics.
After STP converges, you discover that traffic from switch SWG toward switch SWD takes a less
optimal path. What can you do to optimize the STP tree in this switched network?

A.
Change the priority of switch SWA to a lower value than the default value.

B.
Change the priority of switch SWB to a higher value than the default value.

C.
Change the priority of switch SWG to a higher value than the default value.

D.
Change the priority of switch SWD to a lower value than the default value.
