Answer: C
The process of applying a mathematical algorithm to the data
that travels in the network and placing the results of this
operation with the hash data is used for controlling data
integrity, since any unauthorized modification to this data
would result in a be different hash. The application of a
digital signature would accomplish the nonrepudiation of the
delivery of the message. The term security is a broad
concept and not a specific one. In addition to a hash and a
digital signature, confidentiality is applied when an
encryption process exists.

Answer / adja
Just like a traditional manual signature, when a message is digitally signed it applied that the receiver agreed on the integrity of that document. You don't sign a document you disagree to. It is Non-Repudiation because this signature is unique to that person and a proof of the person's identity (Authentication). So the a digitally signed document can provide INTEGRITY, NON-REPUDIATION and AUTHENTICATION. From all the answers only "C" provides the right answer
