Which platform can be connected to Analytics to let you test different versions of web pages with specific audiences?

Google Optimize is the correct answer because it is Google's A/B testing and personalization platform. It integrates directly with Google Analytics, allowing users to test different variations of web pages or app experiences with specific audience segments and measure the impact on their Analytics goals. Firebase is a platform for mobile and web app development, offering analytics but not A/B testing for web pages in the same way Optimize does. Search Console helps monitor search performance and identify issues, not conduct A/B tests. "Modify event" is a feature within Google Analytics 4 for altering event data, not a separate platform for A/B testing.
