D Correct answer
Explanation

RARP stands for Reverse Address Resolution Protocol. It finds the logical address for a machine that knows only its physical address.One or more unique logical (IP) address is assigned to host or router and this address is independent from the physical (hardware) address of the machine because it knows the physical address, but not its IP adress, so this is the correct answer.
