What term describes the amount of risk that remains after the vulnerabilities are classified and the

A.

B.
Inherent risk

C.

D.
Impact risk

Explanation:
The residual risk is the risk or danger of an action or an event, a method or a (technical) process that, although
being abreast with science, still conceives these dangers, even if all theoretically possible safety measures
would be applied (scientifically conceivable measures); in other words, the amount of risk left over after natural
or inherent risks have been reduced by risk controls.
