Why each option
Transit traffic is defined as data that enters an ingress port, is compared against the forwarding table, and is then forwarded out an egress port to its destination.
Traffic addressed to the chassis requiring special handling by the RE is known as exception traffic, not transit traffic.
This accurately describes transit traffic, which is data passing through the router from one interface to another, based on forwarding table lookups.
While some transit traffic might trigger ICMP messages, this is not the defining characteristic of all transit traffic.
Traffic requiring special attention that does not pass through the device is typically exception traffic or traffic destined for the device itself, not transit traffic.
