Explanation

A ping flood is a classic DoS attack where an attacker overwhelms a target with a high volume of ICMP echo request (ping) packets, consuming bandwidth and processing resources until the target becomes unresponsive (B). Option A (malware infection) is a separate attack category - malware can be a tool used to launch DoS but is not a DoS type itself. Option C (SQL injection) is an injection attack targeting databases, not availability. Option D (rootkit installation) is a persistence technique for maintaining unauthorized access, unrelated to DoS.
