What is the reason the route is not advertised?

Refer to the exhibit.

R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to 172.16.25.0/24 from R1, but it does not advertise to R3.

What is the reason the route is not advertised?
A . R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.
B . Route reflector setup requires full IBGP mesh between the routers.
C . In route reflector setup, only classful prefixes are advertised to other clients.
D . In route reflector setups, prefixes are not advertised from one client to another.
