Answer: D
D is the correct answer since transmission charges are based
on packets transmitted, not the distance or route traveled.
Passwords and other data can be placed within a packet
making choice B incorrect. Choices A and C are not correct
because a complete message is broken into transmission units
(packets), which are routed individually through the network.
