Answer: B
Digital signatures provide integrity because the digital
signature of a signed message (file, mail, document, etc.)
changes every time a single bit of the document changes,
thus, a signed document cannot be altered. Depending on the
mechanism chosen to implement a digital signature, the
mechanism might be able to ensure data confidentiality or
even timeliness, but this is not assured. Availability is
not related to digital signatures.
