The correct answer is C. In the R82 policy model, URL Filtering is part of the Access Control Policy, specifically in layers where Application Control and URL Filtering are enabled. It is used to control access to websites and URL categories as part of the broader access decision. Option A is wrong because HTTPS Inspection is a separate inspection policy used to decrypt or bypass encrypted HTTPS traffic; URL Filtering may use HTTPS Inspection for better visibility, but it is not part of HTTPS Inspection Policy. Option B is imprecise because “URL Filtering policy” is not the main R82 policy package classification in this question; the blade is managed through Access Control. Option D is wrong because Threat Prevention Policy contains protections such as IPS, Anti-Bot, Anti-Virus, and SandBlast/Threat Emulation-related controls, not URL Filtering as its core policy category.
