Answer-first summary for fast verification
Answer: Web Application - Availability, Latency Database - Availability
Option B is correct because it best suits the application's needs. The web application, being request-driven, benefits from latency and availability as SLIs. For the database, a storage system, the recommended SLIs include latency, availability, and durability. Options A, C, and D are incorrect as durability and coverage are not suitable SLIs for a request-driven web application. Coverage, in particular, is more suited for batch processing systems, making it inappropriate for the gaming application's database.
