How can the vSphere administrator achieve this?

A vSphere administrator added a new interface to a Distributed Router with a subnet of 172.16.10.0/24 and
wants to make this subnet reachable to the rest of the network. How can the vSphere administrator achieve this?

A.
Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area and
redistribute into OSPF the 172.16.10.0/24 subnet

B.
Enable OSPF on the Distributed Router. Configure the uplink interface in the normal area and the new
interface with the subnet 172.16.10.0/24 in a Backbone area.

C.
Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area and
redistribute from OSPF the 172.16.10.0/24 subnet.

D.
Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area and the
new interface with the subnet 172.16.10.0/24 in a normal area.
