Correct answer & explanation
✓
User acceptance testing (UAT).
User acceptance testing (UAT) is the most critical phase for verifying that the mobile banking application meets end-user requirements and functions correctly from their perspective. Unlike other testing phases that focus on technical correctness, UAT involves real users performing actual banking transactions (e.g., fund transfers, balance inquiries) in a production-like environment to validate usability, workflow accuracy, and compliance with business rules. This ensures the application is ready for deployment and will be accepted by its intended audience.
