Understanding Disclosure
Disclosure is a critical concept in various fields, particularly in law, finance, and communication. It refers to the act of making information known, especially regarding sensitive or significant data.

Key Elements of Disclosure
- **Agents**: While agents can be responsible for communicating information, they are not a requirement for disclosure itself. Disclosure can occur directly from one party to another without the involvement of an intermediary.
- **Display**: Displaying information is more about presentation than the act of disclosure. The information must first be disclosed before it can be displayed, meaning display is secondary to the actual act of making information known.
- **Exposition**: This option aligns closely with the concept of disclosure. Exposition involves explaining or presenting information clearly. It is the process through which hidden or secret information is revealed, making it accessible and understandable to others. This is the essence of disclosure.
- **Secrets**: Secrets are what disclosure seeks to unveil. However, the existence of secrets does not constitute disclosure. Instead, it is the act of revealing those secrets that defines the process.

Conclusion
In summary, the correct answer is option 'C' because disclosure fundamentally involves exposition—the act of revealing and clarifying information that might otherwise remain concealed. It is through exposition that information is effectively disclosed, allowing stakeholders to make informed decisions based on the unveiled data.
