Which statement is correct regarding MP-BGP?

A.
MP-BGP can indicate whether an advertised prefix (NLRI) is to be used for unicast routing,
multicast RPF checks or for both using different SAFIs.

B.
MP-BGP uses a single BGP table to maintain all the unicast prefixes for unicast forwarding and
all the unicast prefixes for RPF checks.

C.
MP-BGP can be used to propagate multicast state information, which eliminates the need to
use PIM for building the multicast distribution trees.

D.
MP-BGP enables BGP to carry IP multicast routes used by MSDP to build the multicast
distribution trees.
