Answer:
B. Availability
Explanation:
The three principles of the CIA triad are Confidentiality, Integrity and Availability.
Confidentiality means guiding data or information from getting to the wrong people. In confidentiality, only authorized people are meant to see the data.
Integrity on another hand, makes sure that throughout the life-cycle of a particular information or data, the data/information is kept consistent, accurate, complete and even reliable.
Availability ensures that authorized subjects have prompt, undelayed and uninterrupted access to objects - data or information.
Other options supplied in the question - identification, encryption, layering - are not directly part of the CIA Triad. So the answer to the question is availability.
