Which type of attack sends spoofed UDP packets to the IP broadcast address of a large network?

Explanation:
This describes a Fraggle attack. It relies on sending spoofed UDP packets to the broadcast address of a large network. Because UDP is connectionless, devices on the network will reply to the spoofed source IP, flooding the target with responses. Fraggle is the UDP-based counterpart to Smurf and typically abuses UDP services like echo or chargen on ports 7 and 19 to amplify traffic toward the victim. The other options don’t fit: Smurf uses ICMP, not UDP; a SYN flood targets TCP handshakes and a single port; and teardrop exploits malformed IP fragments rather than broadcast UDP responses.
