Select one answer. You are deciding what video ad solution to use. You want an in-stream and out-stream video ad that is available that has a creative builder and you can test different creative variables. Which video ad solution should you select?

Online Video ads are the correct choice because they offer both in-stream and out-stream video placements, include a creative builder, and allow for A/B testing of different creative variables. This aligns perfectly with the requirements for diverse placement, creative flexibility, and optimization capabilities. Sponsored Brands video is primarily in-stream and lacks the extensive creative testing features. Sponsored Display video is out-stream but has more limited creative builder and testing options compared to Online Video ads. Streaming TV ads are in-stream only and are designed for brand awareness on Fire TV, not for granular creative testing across various placements.
