Comprehensive and Detailed Explanation:
This scenario follows the Privacy by Design (PbD) principle of "Respect for User Privacy - Keep it User-Centric" because it gives users direct control over their personal data, allowing them to access, modify, and manage their information.
Option A (Proactive, not reactive; preventative, not remedial) emphasizes anticipating privacy risks before they arise, which is not the focus of this feature.
Option B (Full functionality - positive-sum, not zero-sum) refers to integrating privacy protections without sacrificing usability or security.
Option D (End-to-end security - full life cycle protection) relates to safeguarding data throughout its entire life cycle, which is not the main principle demonstrated in this scenario.
