The correct answer identifies three types of reactions that are crucial for addressing issues within a Reaction Plan. Compensation actions are typically enacted in response to a problem that has already occurred, serving to mitigate its effects or compensate for its consequences. Corrective actions are intended to address the root cause of a problem, ensuring that it does not recur. Prevention actions focus on implementing measures that stop potential issues from arising in the first place.

These three reaction types work together to create a comprehensive approach to problem-solving and continuous improvement. By compensating for immediate effects, correcting underlying issues, and taking preventive measures, an organization can improve its processes and enhance overall effectiveness.

The other options fail to capture the essence of active responses to issues in a Reaction Plan. They either focus on different aspects of project management or problem-solving that don't directly address the causal and remedial strategies needed in a reaction plan context.
