In the slow start phase of the TCP congestion algorithm, the size of the congestion window:
does not increase
increase linearly
increases quadratically
increases exponentially
In Slow start phase, window size increases by 1 MSS for each received acknowledgement and at the end of RTT, window size increases exponentially. So, (D) is correct option!
Assume that $\text{ssthresh} = 8.$
Increase is exponential in the Slow Start Phase.
Answer is option D.
ans d)
