Consider the following statements:
(i) Address Resolution Protocol (ARP) provides a mapping from an IP address to the corresponding hardware (link-layer) address.
(ii) A single TCP segment from a sender S to a receiver R cannot carry both data from S to R and acknowledgement for a segment from R to S.

Show answer & explanation
Correct answer: B
Answer: (i) is TRUE and (ii) is FALSE.
Explanation for (i): ARP provides a mapping from an IP address to the corresponding hardware (link-layer) address (for example, an IPv4 address to a MAC address) on a local network.
Explanation for (ii): This statement is false. TCP acknowledgements are part of the TCP header and can be piggybacked on segments that also carry data. If a host has received data from its peer, it can send a segment containing its own data and include the ACK number acknowledging the peer's data in the same segment.
Therefore, the correct choice is the option stating that the first statement is true and the second statement is false.
