Why each option
Availability in information security ensures that authorized users have reliable and timely access to information and resources when needed.
This describes integrity, which ensures data is not improperly modified, rather than availability.
Availability, as one of the pillars of information security (CIA triad), specifically ensures that information and information systems are accessible and usable by authorized users when required. This includes ensuring that systems are operational, data is retrievable, and resources are functioning in a timely and consistent manner.
This describes accountability or non-repudiation, which attributes actions to individuals, not availability.
This describes integrity, as it focuses on preventing unauthorized data modifications, even if done by authorized personnel, which is distinct from ensuring access.
