i would go with D, because in option A it says "Initatated by unity", which is wrong, packet reflect is just for packet reply, not for traffic initiated by unity.

A: is correct Packet reflect Packet reflect, available starting in Dell EMC Unity OE version 4.1, is a feature that ensures outbound (reply), packets are sent back to the same host or router as the inbound (request) packet. This enables the NAS server to bypass routing and ARP table lookups when replying to a packet, so no routing configuration is required. With packet reflect, information including the local IP, remote IP, and next-hop MAC address are cached from the incoming packet. When the NAS server replies to that packet, it leverages this information to send the outbound packet to the proper location.
