Suppose the network supports a sender up to a window of 16 packets after which it drops packets. Assume the starting congestion window is 1 packet, and the ssthresh is 8 packets How does TCP congestion window evolve over time (without fast recovery)? O A. cwnd = 1, 2, 4, 8, 16, 32, and the sequence repeats) B. cwnd 1, 2, 4, 8, 9, 10,., 16, 17, (and the sequence repeats) C. cwnd = 1, 2, 4, 8, 9, 10, 16 (and the sequence repeats) D. cwnd 1, 2, 3, 4,..., 16 (and the sequence repeats)
