Which of the following is the MOST useful information for a risk practitioner when planning response activities after risk identification?

A risk register is a comprehensive list of all identified risks, but without prioritization, it doesn't alone tell the practitioner which risks to address first in response planning.

Risk appetite defines the overall level of risk an organization is willing to accept, which is a strategic guiding principle, but it doesn't provide the granular detail needed to prioritize individual risks for specific response activities.

Risk priorities, derived from factors like likelihood and impact, directly indicate which risks are most critical and warrant immediate attention and resources during response planning. This helps allocate efforts effectively, focusing on the highest-ranked risks first.

Risk heat maps are visual representations of risks, often showing their likelihood and impact, which aid in understanding the overall risk landscape and can inform priorities, but the priorities themselves are the actionable data for planning responses.
