Explanation

Non-repudiation ensures that the sender of a message cannot deny having sent it. A digital signature is the mechanism that provides non-repudiation - it cryptographically binds the message to Ann's private key, proving she authored and sent it. Email encryption (A) protects confidentiality but doesn't prove who sent the message. Steganography (B) hides data but doesn't establish accountability. Access control (D) restricts who can act, but doesn't provide proof of an action taken.
