• A. Nondisclosure Statement
• B. National Defense Seal
• C. National Data Security
• D. Not for Disclosure Summary

Answer: (A)

NdS stands for nondisclosure statement. In SCI and security training, a nondisclosure statement is a formal commitment you make acknowledging that you will not disclose restricted or sensitive information to unauthorized individuals or in unauthorized places. It creates a legal and ethical obligation to protect information you access as part of your duties and reminds you of the penalties for improper disclosure. The other phrases listed aren’t standard terms used in this context, as they don’t describe a document or obligation governing confidentiality. When you encounter NdS, you’re affirming your responsibility to safeguard information and to share it only through proper, authorized channels.
