The correct answer is: Skippable in-stream ads and in-feed video ads

Explanation: For potential customers in decision-making moments, skippable in-stream ads and in-feed video ads are two video ad formats optimized to drive action and encourage customers to take meaningful actions that can be measured. Skippable in-stream ads play before, during, or after other videos and allow for the option to skip after 5 seconds. In-feed video ads appear in YouTube search results and the YouTube app Home feed and include an image thumbnail, headline, and text. Both video ad formats allow for interactive features like call-to-action buttons and product feeds, encouraging customers to interact with the brand or business.
