An advertiser has two search campaigns: regular and Dynamic ads. The regular campaign has the keyword “buy flowers,” and the same keyword was selected for the Dynamic campaign. Their combined CTR, bids and quality coefficients match. Which campaign’s ad will appear in search results?

Regular keywords always have priority over Dynamic keywords, so the regular search ad will appear.
This situation is impossible. Dynamic ad campaigns always generate unique keywords that don’t overlap with regular keywords.
The Dynamic ad will appear because it responds to the user’s query better by showing the keyword in the ad title.
