    Correct Answer: A

    The primary reason for using a digital signature is to authenticate the sender of a message.

The question in the Ref Manual is only about the change. In the question posed here, however, the identity of the *receiver* is also listed under C. If so, the originator/sender should be listed here, then the option would be ok, but not the receiver. This leaves A. as the only valid one. All three chatbots ChatGPT, MS-Copilot and Google-Gemini also output A. as the answer.
