The correct answer is B. Ping of death attack. The Ping of Death attack involves sending oversized ICMP packets that exceed the maximum legal IP packet size of 65,535 bytes, causing buffer overflows and system crashes upon reassembly.

Why each option
The Ping of Death attack involves sending oversized ICMP packets that exceed the maximum legal IP packet size of 65,535 bytes, causing buffer overflows and system crashes upon reassembly. Sending fragmented ICMP packets that reconstruct to over 65,536 bytes is the defining characteristic of this attack.
A Fraggle attack uses UDP packets sent to broadcast addresses to amplify traffic and flood a target, and does not involve oversized ICMP packet fragmentation.
The Ping of Death exploits the fact that while IP packets cannot legally exceed 65,535 bytes, fragmented ICMP packets can be crafted so their reassembled size exceeds this limit, causing a buffer overflow on the target system when it attempts to reassemble the oversized packet.
A SYN Flood attack exploits the TCP three-way handshake by sending large numbers of SYN requests without completing the connection, and does not involve ICMP packets or packet size manipulation.
A Land attack sends a TCP SYN packet with identical source and destination IP addresses and ports to cause the target to loop, which is unrelated to oversized ICMP fragmentation.
