Non-Repudiation
Suggested answer: D

Explanation:

Non-repudiation is the assurance that someone cannot deny the validity of something. Nonrepudiation is a legal concept that is widely used in information security and refers to a service, which provides proof of the origin of data and the integrity of the data. In other words, nonrepudiation makes it very difficult to successfully deny who/where a message came from as well as the authenticity and integrity of that message.
