Explanation:
The correct SLIs for this application are Web Application - Availability, Latency and Database - Availability. These indicators are ideal because the web application is request-driven, making latency and availability appropriate SLIs. For the database, which is a storage system, the recommended SLIs are latency, availability, and durability. Options A, C, and D are incorrect because durability and coverage are not suitable SLIs for a request-driven web application. Coverage is more suited for batch processing systems, not for the database of a gaming application. Reference: Service Level Objectives (Indicator in Practice).
