1 1 vote In TCP, acknowledgement no always suggest the next sequence no it wants (means if ack no=1024 which mean 1023 packet are received and it receiver want 1024 as next seq no.) And as 3rd is erroneous it will ask for the same packet hence I think the answer should be (D). Please correct me if I am wrong about the concept of acknowledgment in TCP.
