sorry A
In this document third point says about counters.

Answer A seems to be correct.

You can configure an interface-specific firewall filter only on a port or a Layer 3 interface as an interface-specific firewall filter is not supported for a VLAN.
Can someone confirm the answer? I feel like it should be D.
