哪项功能支持您衡量成效、查看完整指标、开启转化优化，并凭借更深入的洞察来微调您的推广活动？

Audience Insights (目标客户洞察) is the correct answer because it provides comprehensive data on your audience, allowing you to measure performance, view full metrics, enable conversion optimization, and gain deeper insights to refine your campaigns. This feature goes beyond basic statistics by offering detailed demographic, professional, and behavioral information about your target audience. Campaign Statistics (推广活动统计信息) offers performance data but lacks the depth for conversion optimization and campaign refinement. Conversion Tracking (转化追踪) focuses specifically on conversions but doesn't provide the broad audience insights needed for holistic campaign adjustments. The option "No feature can provide such data" is incorrect as Audience Insights is designed for this purpose.
