B . Risk
C . Vulnerability
D . Dependency

Answer: A

Explanation:

A possible event that can have a disruptive effect on the reliability of information is a threat. A threat is anything that has the potential to harm an asset or its protection, such as a natural disaster, a human error, a malicious attack, etc. A threat can exploit a vulnerability or weakness in an asset or its protection and cause an adverse impact on the confidentiality, integrity or availability of information. ISO/IEC 27001:2022 defines threat as “potential cause of an unwanted incident, which can result in harm to a system or organization” (see clause 3.48).
