Consider the following statements regarding the slow start phase of the TCP congestion control algorithm. Note the cwnd stands for the TCP congestion window and MSS denotes the Maximum Segment Size. i.

Which one of the following is correct?

A. Only ii and iii are true

B. Only i and iii are true

C. Only iv is true

D. Only i and iv are true

C. Only iv is true

cwnd is approximately doubles every round-trip time. So option C is correct answer
