How does optimized targeting support a cookieless world?

Optimized targeting supports a cookieless world because it shifts reliance away from third-party cookies, which are becoming obsolete due to privacy regulations and browser changes. Instead, it leverages first-party data (data collected directly by the advertiser), Google's extensive audience signals, and machine learning to identify and reach relevant customers. This approach allows for effective targeting without needing to track individual users across different websites using third-party cookies. The other options are incorrect because optimized targeting does not focus on users who accept tracking, it is not solely dependent on Google Analytics 4 for its cookieless functionality, and it does not permit third-party cookies without user consent.
