How does the 802.11 data frame indicate how a large packet should be fragmented?
A) It uses the preamble header to estimate the ideal packet size.
B) The frame check sequence dictates the calculated packet size.

The sequence control field in the 802.11 data frame indicates how packets greater than the maximum transfer unit (MTU) size will be fragmented. The field contains a Fragment Number and a Sequence Number that are used to identify fragmented packets and their order for reassembly by the receiving station. The duration field is used to reserve the wireless medium for transmission and does not dictate how packets should be divided. The preamble header and frame check sequence do not provide information on how to fragment packets.
