Explanation:

Availability relates to information being available when required by the business process in present
as well as in future. Resilience is the ability to provide and maintain an acceptable level of service
during disasters or when facing operational challenges. Hence they are most closely related.
Answer B is incorrect. Confidentiality deals with the protection of sensitive information from
unauthorized disclosure. While the lack of system resilience can in some cases affect data
confidentiality, resilience is more closely linked to the business information requirement
of availability.

to its validity in accordance with business values and expectations. While the lack of system
resilience can in some cases affect data integrity, resilience is more closely linked to the business
information requirement of availability.

business process as well as being delivered in a timely, correct, consistent and usable manner.
While the lack of system resilience can in some cases affect effectiveness, resilience is more
closely linked to the business information requirement of availability.
