Refer to the exhibit. R2 is mutually redistributing between EIGRP and BGP. Which configuration is necessary to enable R1 to see routes from R3?
A. The R3 configuration must include ebgp-multihop to the neighbor statement for R2.
B. The R2 BGP configuration must include bgp redistribute-internal.
C. R1 must be configured with next-hop-self for the neighbor going to R2.
D. The AS numbers configured on R1 and R2 must match.

This example from Cisco doesn’t mention “redistribute internal” as a requirement for mutual redistribution.
R2 would need the redistribute-internal for R3 to get routes from R1, not the other way around. The only answer that makes sense is D.
Answer is B
AS numbers have nothing to do with it as redistributing between two different protocols so not D
B is correct as whenever you redistribute from BGP to something else, BGP will only release externally learned routes
