A sender is sending data to the receiver over a half-duplex link.Transmission time for data packets sent from sender to receiver is 80 μs. The propagation delay over the link is 280 μs. What frame size is required for the sliding window protocol with a window size of 8 packets to achieve throughput of 40 x 106 bits per second.

A) 1800 B

B) 225 B

C) 250 bits

D) 2000 bits

this is such a low quality question. How can efficiency be more than 100%?

many have told 1+a is used here bcz channel is half - duplex but Even in STOP AND WAIT protocol which works on half duplex we use 1+2a there , why not here .Please clear my doubt
