Explanation:

Requirement Analysis
Sales table # Users should only see sales data for their own region.
This requires filtering rows based on a condition (e.g., Region = User's Region).
The correct feature: Row-level security (RLS).
Employees table # Restrict access to Personally Identifiable Information (PII) while allowing access to non- sensitive columns.
This requires restricting access to specific columns (such as SSN, phone, address, etc.), but leaving others visible.
The correct feature: Column-level security.
Maintain access to unrestricted data for all users # Both RLS and column-level security allow users to continue accessing non-restricted data.
Why Other Options Are Not Correct
Item permissions: Control access at the object level (e.g., table or report), not at the row or column level. Too coarse for this requirement.
Workspace permissions: Apply at the workspace level, not suitable for table-level data filtering.
Completed Answer
Employees # Column-level security
Sales # Row-level security (RLS)
