Q26

Suppose we are transmitting frames between two nodes using Stop-and-Wait protocol. The frame size is $3000$ bits. The transmission rate of the channel is $2000$ bps (bits/second) and the propagation delay between the two nodes is $100$ milliseconds. Assume that the processing times at the source and destination are negligible. Also, assume that the size of the acknowledgement packet is negligible. Which ONE of the following most accurately gives the channel utilization for the above scenario in percentage?
