In the diagram below, SAP 1 is put into the blocking state as a result of the spanning tree protocol. What will occur in the VPLS instance if SAP 2 goes down and SAP 1 transitions to the forwarding state? Select the most accurate statement.

• A.A Spanning Tree BPDU will be sent across the mesh flushing the FDB table in all devices participating in the VPLS instance.
• B.An LDP control message will be sent to all devices in the mesh participating in the VPLS instance. Only MAC addresses associated with the PE that the failure occurred on will be flushed.
• C.An LDP control message will be sent to all devices in the mesh participating in the VPLS instance. The entire FDB in the VPLS instance will be flushed.
• D.Stale information will be used within the VPLS instance to forward traffic until the FDB ages out.
