check attached (Please notice that the question says that the 5th segment is lost!!!!!!!!)

Compare GBN, SR and TCP (no delayed ACK). Assume that the timeout values channel) by the receiving host (Host B) and the sending host (Host A) correctly received by Host B for all three protocols are sufficiently long such that 10 consecutive data segments and the corresponding ACKs can be received (if not lost in the respectively. Suppose Host A sends 10 data segments to Host B, and the fifth a. How many segments has Host A sent in total and how many ACKs If the timeout values for all three protocols are much longer than 10 segment (sent from A) is lost. In the end, all 10 data segments have beer has Host B sent in total? What are their sequence numbers? Answer this question for all three protocols b. RTT, then which protocol successfully delivers all 10 data segments in the shortest time interval
