Consider two hosts P and Q connected through a router R. The maximum transfer unit (MTU) value of the link between P and R is 1500 bytes and between R and Q is 820 bytes. A TCP segment of size 1400 bytes is transferred from P to Q through R with an IP identification value of 0x1234. Assume that the IP header size is 20 bytes and the Don't Fragment (DF) flag is not set. Which of the following statements is/are true? A. Two fragments are created at R and the IP datagram size carrying the second fragment is 620 bytes. B. If the second fragment is lost, R resends only that fragment with an IP Identification value of 0x1234. C. If the second fragment is lost, P is required to resend the entire TCP segment. D. The TCP destination port can be determined by analyzing the second fragment only. Choose the correct answer from the options given below:
