Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network. For example, in IP Version 4, the most common level of IP in use today, an address is 32 bits long. In an Ethernet local area network, however, addresses for attached devices are 48 bits long. (The physical machine address is also known as a Media Access Control or MAC address.) A table, usually called the ARP cache, is used to maintain a correlation between each MAC address and its corresponding IP address. ARP provides the protocol rules for making this correlation and providing address conversion in both directions.

ARP - Address Resolution Protocol
ARP is a protocol used to map an IP address to a physical or MAC address. It is a communication protocol used in a computer network to find the MAC address of a device from its IP address.
Finding the MAC address that corresponds to an IP address
The correct answer is option D, which states that ARP is used for finding the MAC address that corresponds to an IP address. ARP is used to resolve IP addresses to MAC addresses, which are unique identifiers for devices on a network. ARP maintains a table of IP addresses and their corresponding MAC addresses, called the ARP cache or ARP table.
When a device wants to communicate with another device on the network, it needs to know the MAC address of the destination device. The device sends an ARP request to the network, asking for the MAC address of the device with the specified IP address.
The ARP request is broadcasted to all devices on the network, and the device with the specified IP address responds with its MAC address. The requesting device receives the MAC address and stores it in its ARP cache, so it can communicate directly with the destination device.
Conclusion
In conclusion, ARP is a protocol used to map an IP address to a physical or MAC address. It is used to find the MAC address that corresponds to an IP address. ARP maintains a table of IP addresses and their corresponding MAC addresses, called the ARP cache or ARP table. When a device wants to communicate with another device on the network, it sends an ARP request to the network, asking for the MAC address of the device with the specified IP address.
