Framesof 1000 bits are sent over a $$10^{6}$$}bps duplex link between two hosts. The propagation time is 25 ms. Frames are to be transmitted into this link to maximally pack them in transit (within the link).What is the minimum numberofbits (i) that will be required to represent the sequence numbers distinctly? Assume that no time gap needs to be given between transmission of two frames.

A

i=2

B

i=3

C

i=4

D

i=5
