Explanation

Power Fx is the low-code formula language used in Power Apps canvas apps to control app behavior, logic, and data transformations. To mask a social security number and display only the last four digits when a user moves to a different field, you would write a Power Fx expression (e.g., using Right() or text manipulation functions) on the control's OnChange or Default property. Option A (Business rule) is primarily used in model-driven apps for field validation and visibility, not canvas apps. Option B (Business process flow) is a guided multi-stage process tool, not a data masking mechanism. Option C (Power BI DAX) is a formula language specific to Power BI data modeling and has no role in Power Apps canvas app configuration.
