B.If there exists no unicast equal-cost routes, multicast load balancing fails.

C.Balanced distribution of entries over equal-cost routes can be ensured as long as multicast load balancing is performed.

D.If group address-based load splitting is employed, balanced distribution of entries over equal-cost routes cannot be ensured due to hash function limitations.
