Correct answer & explanation
✓
Canvas app
Canvas apps allow flexible formulas, such as DateDiff, to automatically calculate the number of days between two dates, making them ideal for forms requiring custom calculations. Option A is wrong because Power Apps portal is designed for external-facing websites, not internal employee forms. Option C is wrong because Power Automate is an automation tool, not a form-building app. Option D is wrong because model-driven apps use standardized forms and custom calculations are less straightforward compared to canvas apps.
