你的客戶想要開始實行他們的隱私權策略。 隱私權方面的持續變動有可能影響資料的收集方式，而客戶目前可以採取哪一項因應措施？

The correct answer is "透過強化轉換準確評估資料，減少資料損失" (Enhance conversion measurement to reduce data loss). As privacy regulations evolve, traditional data collection methods are becoming less reliable. Enhanced conversion measurement, such as Google's Enhanced Conversions, uses hashed, first-party data to improve the accuracy of conversion tracking while respecting user privacy. This helps advertisers maintain measurement accuracy despite data limitations. "開始與重要的廣告聯播網夥伴合作，發展完備的第三方廣告空間" (Start collaborating with key ad network partners to develop robust third-party ad space) is less directly about immediate privacy strategy implementation and more about future advertising infrastructure. "透過複雜的手動系統 (例如聯播網式再行銷) 啟用資料" (Activate data through complex manual systems, such as network-based remarketing) suggests a less efficient and potentially less privacy-compliant approach than enhanced measurement. "推出計畫來追蹤使用者在各種作業系統裝置上，從應用程式切換到網頁的行為" (Launch a plan to track user behavior across various operating system devices, from app to web) describes cross-device tracking, which is becoming increasingly challenging due to privacy changes, not a solution to mitigate data loss.
