* Option A (Origin assurance): Digital signatures ensure that the code originates from a trusted source. * Option B (Integrity verification): Digital signatures verify that the code has not been tampered with since it was signed. * Option C (Confidentiality): Digital signatures do not provide encryption or confidentiality. * Option D (DRMs): Digital signatures are not specifically related to Digital Rights Management. * Option E (Recipient verification): Digital signatures validate the sender, not the recipient. * Option F (Free of malware): While digital signatures verify integrity, they cannot guarantee that the code is free of malware.
