D is correct.

You can configure ACLs at different stages of the traffic processing pipeline. Depending on the FortiSwitch model, there are up to three different stages you can configure ACLs on:
Ingress: This is the second stage for ingress traffic. It supports a higher number of actions.

Prelookup: This is the first stage in the pipeline for ingress traffic. It takes place before the switch performs layer 2 and layer 3 lookups, and it supports a reduced number of actions. If the action you need is supported at this stage, then in most cases, it is better to apply the action at this point, before the switch handles the traffic any further.

Egress: Actions are applied on egress traffic only.
