How is SNCP and MS-SPRing traffic rerouted during a protection switch when a complete fiber cable cut occurs？（）
A
SNCP traffic is switched from the first node that recieves the AIS. MS-SPRing traffic is rerouted from the first in the ring.
B
SNCP traffic is selected at the destination node in the ring. MS-SPRing is rerouted from the originating node in the ring.
C
SNCP traffic is rerouted from the originating node in the ring. MS-SPRing traffic is rerouted from the originating node in the ring.
D
SNCP traffic is selected at the destination node in the ring. MS-SPRing traffic is rerouted from the last reachable node in the ring.
