   A team is launching a mobile payment app that uses NFC for contactless payments and the fingerprint sensor for authentication. The target market includes a low-cost device that has NFC but a very slow fingerprint sensor. The team has a limited budget and must choose between (1) optimizing the fingerprint authentication flow and (2) expanding NFC test coverage to more devices. Which decision is most justified?

   • ASplit the budget equally because both features are equally critical to the app's success
   • BPrioritize fingerprint optimization because a slow sensor will cause user frustration and app abandonment
   • CDefer both and focus on the app's UI design to attract more users
   • DPrioritize NFC test coverage because contactless payment is the core feature and a failure there is a critical defect
