Explanation

Campus Fabric Core-Distribution is the right fit because it's specifically designed for mixed environments where core/distribution switches run EVPN-VXLAN while access switches do not - exactly matching the two EVPN-VXLAN core devices and two non-EVPN-VXLAN access switches described.

Why the distractors are wrong:

• A (EVPN Multihoming) is a redundancy feature within EVPN (connecting a host to multiple PE devices), not a Mist campus fabric topology - it's not a design option in this context.
• C (3-Stage IP Clos) and D (5-Stage IP Clos) are spine-leaf architectures where all switches, including access layer devices, must support EVPN-VXLAN. Since the access switches here lack that capability, neither Clos design is viable.

Memory tip: Think "Core-Distribution = Core does the VXLAN work." When only your core/distribution layer speaks EVPN-VXLAN and your access switches are traditional, Core-Distribution is your answer. IP Clos designs demand EVPN-VXLAN end-to-end - if access switches can't do it, Clos is out.
