   A startup is building a mobile app that requires a very tight integration with the device's Bluetooth Low Energy (BLE) stack for a custom hardware accessory. They have a small team with experience in both web technologies and C#. They need to launch on both iOS and Android quickly. Which development approach is the most suitable, considering the need for deep BLE integration and the team's skills?

   • AUse Xamarin.Forms and write custom native BLE implementations for each platform using C#
   • BUse Flutter and rely on the community's BLE plugins
   • CBuild two separate native apps, one in Swift and one in Kotlin
   • DUse a hybrid WebView-based approach with a JavaScript BLE library

   A company has a successful native iOS app and wants to expand to Android. They have a limited budget and a tight deadline. They are considering using a cross-platform framework to reuse code. The app heavily uses the iOS-specific 'Haptic Touch' feature for a unique user interaction. Which approach is the most pragmatic to meet the deadline and budget while still delivering a quality Android app?

   • ABuild a separate native Android app in Kotlin, copying the design and logic from the iOS app
   • BRewrite the entire app from scratch in Flutter, implementing a custom haptic feedback system for Android
   • CUse React Native to share the business logic and UI, and use a plugin to access Android's haptic feedback API
   • DUse a hybrid WebView-based approach to wrap the existing iOS app's web content
