Please review the following screenshot. This is an example of which post type?

The screenshot displays multiple images that users can swipe through, characteristic of a carousel post. Carousel ads on Reddit allow advertisers to showcase several images or videos within a single ad unit, each with its own headline and destination URL. This format is ideal for telling a story, highlighting different product features, or presenting a collection of items. Free-form is not a standard Reddit ad post type. While a carousel contains images, "Image" refers to a single-image post, not multiple swipeable images. Similarly, "Video" refers to a single video post, not a collection of media that can include images.
