Hello CRIS

The answer is

[C] Packet Destination

One of the mechanisms of IP is fragmentation and reassembly.  Under certain  circumstances,  a  datagram  originally transmitted as a single unit will arrive at its final destination broken into several fragments. The IP layer at the receiving host must accumulate these fragments until enough have arrived to completely reconstitute  the  original  datagram.

Hello,
I think the right answer is C. The fragments are reassembled into the original IP packet only after they are transmitted to the destination.
I hope this helps.
