  2. A Cryptographic way of remotely signing a document.
  3. A mathematical way of verifying the authenticity of a document.
  4. A way to protect the user from themselves.
Explanation
Answer: C - A digital signature is a mathematical way of verifying the authenticity of a document

Key Takeaway: Digital Signing should be used with documents where the authenticity of the document must be determined. One of the most common places to see this is when installing hardware drivers on modern Microsoft Windows systems. If the driver is not digitally signed, Windows throws an error and a message box about it, letting you continue at your own risk.
