What is a benefit of enabling tandem multicast replication for SPBM?

A.
Multicasts follow a better path to each destination than they would with head-end replication.

B.
An ingress SPBM switch does not have the load of replicating and forwarding many copies of a
multicast.

C.
An ingress SPBM switch can load-balance multicasts over multiple equal-cost paths to a destination,
even when the multicasts belong to the sameI-SID.

D.
SPBM switches can send multicasts as both multicasts and unicasts, increasing reliability for the
transmission.
