Final answer:
The correct answer is Option 1: Teardrop, which describes a specific DoS attack where an attacker sends fragmented ICMP packets that the target cannot reassemble.
Step-by-step explanation:
In this type of DoS attack, the attacker creates malicious ICMP packets that are fragmented in a way that the target machine is unable to reassemble them correctly, typically resulting in the system crashing or becoming unstable. The correct answer to the question is Option 1: Teardrop. The Teardrop attack takes advantage of a vulnerability in the IP fragmentation reassembly process where the overlapping fragments cannot be properly reassembled, and thus the system may fail.
