Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It prevents users from having conflicting roles that could lead to fraud
RBAC naturally supports separation of duties by assigning permissions to roles and ensuring that conflicting roles (e.g., approving and executing payments) are not assigned to the same user. This reduces fraud risk.
