`Hey,
Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries
Public Key Infrastructure (PKI) ensures that an author cannot refute that they signed or encrypted a particular message once it has been sent, assuming the private key is secured. Here Digital signatures link senders to their messages. Only the sender of the message could sign messages with their private key and therefore, all messages signed with the sender's private key originated with that specific individual.
So, OPTION C IS CORRECT
Kindly revert for any queries
Thanks.
