A Denial of Service (DoS) attack aims to make a system or service unavailable to its intended users, disrupting normal operations. Companies with online services are prominent targets since their revenue and reputation depend heavily on maintaining website uptime and service availability. Home users can also be affected, especially if they operate IoT devices or run their services from personal networks, making them susceptible to attacks that exploit their vulnerabilities. Educational institutions are increasingly becoming targets as they provide online resources and services to students and staff, and failures can disrupt learning and administrative operations.

Choosing "All of the above" reflects the reality that a DoS attack can impact a diverse range of audiences, as attackers look for any target that can be disrupted for various reasons, including financial gain, political motives, or just for the challenge of it. Each of these groups, due to their different services and dependencies on network accessibility, are potential victims. Hence, the inclusivity of "All of the above" captures the wide-ranging scope of potential victims of DoS attacks effectively.
