Why each option

The `accept` and `discard` actions in Junos firewall filters are terminating actions that dictate the fate of a packet and stop further evaluation by that filter.

Apermit

`permit` is not a standard terminating action in Junos OS firewall filters; `accept` is the correct action to allow traffic.

BacceptCorrect

The `accept` action explicitly allows the packet to pass through the filter and continue processing by the system, effectively terminating the filter's evaluation for that packet.

Cdeny

`deny` is not a standard terminating action in Junos OS firewall filters; `discard` or `reject` are used to deny traffic.

DdiscardCorrect

The `discard` action silently drops the packet, preventing it from passing further, and thus terminates its processing by the firewall filter without sending any notification.
