Which of the following is a Unity service used to analyze player engagement?

Unity Analytics is the correct choice because it is specifically designed to gather and analyze data related to player engagement and behavior within a game. This service provides developers with insights into how players interact with their games, which can include metrics such as session duration, player retention, and in-game actions. By using Unity Analytics, developers can make informed decisions to enhance gameplay, improve user experience, and tailor content based on actual player behavior.

Unity Collaborate is focused on team collaboration, allowing multiple developers to work together on the same project efficiently. Unity Ads is a monetization service designed to help developers integrate ads into their games and generate revenue. Unity Cloud Build automates the process of building and deploying games but does not provide tools for analyzing player engagement or behavior. Each of these services has a distinct purpose, which is essential for developers to understand in order to leverage Unity’s ecosystem effectively.
