Explanation

Flooding a target with TCP SYN requests is a SYN flood, a classic form of denial-of-service (C) attack - it exhausts the target's connection table by initiating handshakes that are never completed, making the service unavailable to legitimate users.

A (table poisoning) refers to corrupting lookup tables like ARP or DNS caches to redirect traffic, not flooding connections.
B (reconnaissance) is passive information gathering (scanning, enumeration) - the opposite of an active flood attack.
D (IP spoofing) is a technique often used within SYN floods (to fake source IPs), but spoofing alone doesn't flood or deny service.

Memory tip: Think DoS = Deny Others Service - any attack whose goal is making a resource unreachable (including SYN floods) falls under denial-of-service.
