Your organization is developing a mobile app and wants to select a (Digital Leader)

Correct answer: B) Firebase.
Firebase is a mobile and web application development platform developed by Google. It provides a variety of tools and services that can help in the development, growth, and management of your app. Firebase offers a suite of cloud-based services that are designed to work together to help you build, improve, and grow your app. These services include:

Firebase Authentication: Helps you authenticate users to your app.
Cloud Firestore: A NoSQL cloud database to store and sync data for client- and server-side development.
Firebase Realtime Database: A cloud-hosted database that supports data sync across clients in realtime.
Firebase Storage: Provides secure file uploads and downloads for your Firebase apps.
Firebase Cloud Messaging (FCM): Allows you to send notifications and messages to your users across platforms.
Firebase Analytics: Provides insights on app usage and user engagement.
Firebase is particularly well-suited for mobile app development due to its ease of use, scalability, and integration with other Google services. It offers a comprehensive set of tools that can help in various aspects of app development, from backend services to user authentication and analytics.

While Google Kubernetes Engine (GKE) is excellent for deploying, managing, and scaling containerized applications, it might be overkill for a simple mobile app without a significant need for container orchestration. Cloud Functions are more suited for event-driven computing, and App Engine is a fully managed serverless platform, which might not offer the same level of control and flexibility as Firebase for mobile app development.

Therefore, for a mobile app that requires a fully featured cloud-based compute platform, Firebase is the most appropriate choice.
