Option A is correct. The EVPN-IRB is using the interface-ful unnumbered model, so there must be an MP-BGP session established between the PEs to advertise VPN-IPv4 routes.

I'm not sure, but I think option A could also be false because the MP-BGP session should support the advertisement of VPN-IPv4 routes, not just VPN-IPv4 routes.

I agree with Curt, option D seems incorrect because the routing table entry should not be resolved using a transport tunnel towards PE.
