Answer

(i) TCP guarantees a minimum communication rate is FALSE.

Explanation

TCP provides reliable, ordered byte-stream delivery and uses congestion control, but it does not guarantee a minimum data rate. Actual throughput depends on network capacity, congestion, receiver conditions, RTT, and other factors.

The remaining statements are true:

  • TCP provides in-order delivery using sequence numbers.
  • TCP reacts to congestion by reducing its congestion window.
  • TCP uses retransmission when data is considered lost.

Final answer: (i).
