您的航空公司客户正使用 Feed 数据为其 Search Ads 360 广告系列模板添加数据结构。其业务目标是有竞争力的机票价格，所以希望广告系列重点宣传这一点。 通过 Feed 可选用的定价选项是什么？

The correct answer is "Average price per route." Search Ads 360 feed-driven templates can dynamically generate ads using data from your feeds. To highlight competitive pricing, the average price per route is a practical and common metric to include in ad copy or for bidding strategies. While "price option per route" is vague, "lowest price per route" might not always be available or sustainable for every ad impression, and "highest price per route" would be counterproductive to the goal of competitive pricing. The average price provides a realistic and appealing data point for potential customers.
