The correct answers are: Greater flexibility and More relevance

Explanation: Responsive search ads offer a distinct advantage by allowing advertisers to experiment with multiple headlines and descriptions. With the ability to input up to 15 headlines and four descriptions, Google Ads employs machine learning to test different combinations, determining which performs the best. This provides immense flexibility in ad creation. Additionally, by collaborating with Smart Bidding and broad match, responsive search ads ensure higher relevance, matching the right ad with each specific query, even ones that static ads might miss.
