Only one community VLAN can be mapped to a primary VLAN.
C.

D.
Multiple community VLANs can be mapped to a primary VLAN.
Only one isolated VLAN can be mapped to a primary VLAN–since the isolated VLAN itself is isolated, it makes no sense to have multiple isolated VLANs, as you should just be able to reuse the single isolated VLAN for hosts that you want to be in the ‘isolated’ state who can only talk to promiscuous ports (usually the DG).
