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.
