This IDS defeating techniques works by splitting a datagram or packet into multiple fragments and the IDS will not spot the true nature of the fully assembled datagram. the datagram is not reassembled until it reaches its final destination. It would be a processor-intensive task for an IDS to reassemble all fragments itself, and on a busy system the packet will slip through the IDS onto the network. what is this technique called?

A. IP routing or packet dropping
B. IP splicing or packet reassesmbly
C. IDS spoofing or session assembly
D. IP fragmentation or Session splicing
