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 might be able to ensure data confidentiality or
even timeliness, but this is not assured. Availability is
not related to digital signatures.
