Explanation

Non-repudiation is one of the security methods that is used to acknowledge the data delivery. It is a method of providing an acknowledgement to the sender of the data and an assurance of the sender's identity to the receiver, so that neither sender nor the receiver can later deny the data having processed by them. Nowadays, non-repudiation is achieved through digital signatures, as it ensures that the data or information, being transferred, has been electronically signed by the purported person (receiver). It also ensures the furnishing of the signature by the sender since a digital signature can be created only by one person. Answer options C, D. and B are incorrect. These are not valid options.
