B is misleading, it should be a non-zero overlay index.

I’m uncertain about the SBD IRB interfaces part; I think it could be a trick option, but I need to double-check that.

I’m pretty confident that EVPN MAC/IP routes are meant to advertise local host addresses, so that might be true.

I think I remember that EVPN routes are tied to service labels, but I'm not sure if it's specifically for SBD VPLS.

I've got a good handle on EVPN, so I think I can tackle this. I'll carefully evaluate each option and identify the one that is false based on my understanding of the EVPN architecture.

Okay, let me think this through step-by-step. EVPN routes are advertised with a service label, so option A is likely true. The gateway IP address in IP-Prefix routes is usually non-zero, so option B is also likely true. Options C and D seem to be describing the purpose of EVPN MAC/IP routes, so I'll need to double-check those.
