Final answer:
In risk management, risks that are high frequency and high severity are best to be avoided to prevent severe disruption to an organization's operations.
Step-by-step explanation:
According to the simple frequency-severity matrix for risk management technique selection, risks that are high frequency and high severity should be avoided. In risk management, the aim is to manage risks in a way that they do not materially impact an organization's ability to operate or achieve its objectives. If a risk is both frequent and severe, it has the potential to severely disrupt operations and therefore, the best approach is usually to avoid such risks altogether. Avoidance can include not engaging in certain activities or finding alternative strategies that do not expose the entity to such high-level risks.
