Which type of agreement is also referred to as a "no disclosure agreement"?

A confidentiality agreement is specifically designed to protect sensitive information from being disclosed to unauthorized parties. By its nature, this agreement restricts the sharing of certain information, hence the reference to it as a "no disclosure agreement." It establishes a legal framework that ensures parties involved are committed to keeping the shared information private, which is crucial in business environments where proprietary knowledge and trade secrets are often exchanged.

In contrast, the other options do not inherently focus on the protection of confidential information. Explicit and directed changes relate to modifications to the terms of a contract and do not address confidentiality directly. A cure notice is a formal notification that a party is in breach of the contract and provides an opportunity to rectify the situation, which also does not pertain to confidentiality. Therefore, the confidentiality agreement aligns perfectly with the concept of preventing disclosure of sensitive information, thus making it the correct choice.
