The correct answer is ARP poisoning. ARP poisoning is an attack where the attacker sends false ARP messages over a local area network. This results in the linking of an attacker's MAC address with the IP address of a legitimate computer or server on the network. Once the attacker's MAC address is associated with an IP address, the attacker will begin receiving any data that is intended for that IP address, enabling interception and possible modification of the data. The other options, such as DNS poisoning and URL redirection would not be conducted on Layer 2, and do not deal directly with the resolution of IP addresses to MAC addresses.
