Answer: Data masking policies

The question requires allowing some users to see full PII while restricting others from seeing the full values. Data masking policies (Option B) are specifically designed for this purpose - they can dynamically mask sensitive data based on user roles or attributes, showing full values to authorized users and masked/partial values to others. Row access policies (Option A) control access to entire rows, not partial visibility of column values. Data encryption (Option C) protects data at rest/in transit but doesn't control visibility. Role-based access control (Option D) manages permissions but doesn't provide granular masking capabilities. The community discussion strongly supports B with 85% consensus and multiple upvoted comments explaining that masking policies allow selective visibility while row policies control row-level access entirely.
