What are two reasons why a marketer might use responsive display ads? Choose two.

Responsive Display Ads (RDAs) offer extended reach because they automatically adjust their size, appearance, and format to fit almost any available ad space across the Google Display Network, including both native and non-native inventory. This adaptability allows them to serve in more ad slots than static image ads. They are also considered cost-effective because the automated optimization of ad creatives often leads to improved performance, potentially generating more conversions at a similar or even lower cost per acquisition compared to other display ad formats. "Guidance" is incorrect because RDAs automatically adapt; users don't need to adjust anything. "Improved communication" is incorrect as RDAs are for advertising, not for real-time customer service or automated query responses.
