Which of the following BEST enables senior management lo compare the ratings of risk scenarios?

Key Risk Indicators (KRIs) track changes in risk levels over time, but they don't provide a direct comparative view of multiple, distinct risk scenarios in the way a heat map does.

Key Performance Indicators (KPIs) measure the effectiveness of processes or activities against objectives, which is different from comparing risk scenarios.

Control Self-Assessment (CSA) is a process where management and staff evaluate the effectiveness of controls, not a tool for directly comparing aggregated risk scenario ratings.

A risk heat map provides a clear, graphical representation of different risk scenarios based on their likelihood and impact ratings, allowing senior management to quickly grasp and compare the relative severity and priority of multiple risks across the organization at a glance.
