Answer 1

Bid adjustments (audiences, website visitors, mobile devices) are available in campaigns for any type of sites. Impressions based on the audience selection condition (segments, audiences, retargeting) are available in ads for YAN. You can check it yourself in the campaign and ad settings interface.
Therefore, the correct answer is "Impressions by condition on the search".
