IPv6 handles the possibility of fragmentation by requiring the:

A. sending host to discover the size of the path MTU and create packets within that size

B. sending host to create packets that will fit in the smallest known MTU of any network

C. routers along the delivery path to fragment packets as necessary to fit within the MTU of the hardware on the outbound port

D. sending host to specify (in an extension header) how the routers should fragment the data

E. none of these
