Explanation
The protection of information from unauthorized access or disclosure is known as confidentiality. This is because confidentiality is one of the three main objectives of information security, along with integrity and availability. Confidentiality ensures that information is accessible and readable only by those who are authorized and intended to do so, and prevents unauthorized or accidental exposure of information to unauthorized parties. The other options are not the protection of information from unauthorized access or disclosure, but rather different concepts or techniques that are related to information security, such as access control (A), cryptography (B), or media protection C.
