As shown in the figure, on the network running the RSTP protocol, the original root port of the SWC is faulty and the port is in the Down state. In this case, the network goes through which processes to achieve stability?

As shown in the figure, on the network running the RSTP protocol, the original root port of the SWC is faulty and the port is in the Down state. In this case, the network goes through which processes to achieve stability?

A . The prepared port on the SWC becomes the new root port and enters to Forwarding state after passing through the Learning state.
B . The prepared port on the SWC becomes the new root port and enters to Forwarding state directly.
C . SWC newly elects the root port and enters to Forwarding state after learning.
D . SWC newly elects the root port and enters to Forwarding state directly.
