Google 政策宗旨的三个主要组成部分是什么？请选择三项。

Google's policy principles are designed to create a safe and beneficial environment for all users and advertisers. "帮助为所有用户打造良好的体验" (Helping to create a good experience for all users) is correct because Google aims for ads to be relevant and non-intrusive, improving the overall user experience. "确保用户安全上网" (Ensuring users are safe online) is correct as Google prioritizes protecting users from malicious content, scams, and privacy violations. "贯彻公平一致的政策" (Implementing fair and consistent policies) is correct because Google strives for transparency and equal application of rules across all advertisers, fostering trust and predictability. "保护商家免受欺诈性扣款的影响" (Protecting merchants from fraudulent deductions) and "保证为商家带来收入" (Guaranteeing revenue for merchants) are incorrect; while Google does offer tools and support for advertisers, these are operational benefits rather than core policy principles that govern the entire ecosystem.
