Refer to the exhibit. Two ISPs have decided to use MSDP and configured routers X and Y (both are PIM RPs) as MSDP peers. In the domain of ISP B, PC A has sent an IGMP membership report for the group 224.1.1.1 and PC B has sent an IGMP membership report for the group 224.5.5.5. Assuming that the MSDP peering relationship between routers X and Y is functional, and given the partial configuration output shown from router X, which two of these statements are true?() 

A.Router X will contain an entry for 224.1.1.1 in its SA cache and will also have an installed (S,G) entry for this in its mroute table.
B.Router X will not contain an entry for 224.1.1.1 in its SA cache but will have an installed (*,G) entry for this in its mroute table.
C.Router X will not contain an entry for 224.5.5.5 in its SA cache but will have an installed (S,G) entry for this in its mroute table.

E.Router X will have no entries for 224.5.5.5 in neither its SA cache nor in its mroute table.
F.Router X will have no entries for 224.1.1.1 in neither its SA cache nor in its mroute table.
