Answer: BD

Explanation:

When connecting two data centers on different subnets using EVPN, MAC addresses need to be advertised between the data centers to maintain Layer 2 connectivity. Using different subnets implies the need for Layer 3 gateways at each site, which typically involve exchanging type-5 routes in an EVPN context.
