I'm not sure about option C. Isn't EVPN-IRB a single service, not a combination of VPRN and VPLSs?

Hmm, option A seems correct. EVPN-MPLS is required for the data plane in EVPN-IRB service.

I believe the correct answer is C) This service consists of a VPRN and multiple VPLSs because EVPN-IRB service does not include VPRN and multiple VPLSs.
