Businesses in the U.S. that have a Brand Store on Amazon will automatically be enrolled in which solution?

The correct answer is "Brand Follow" because businesses in the U.S. that have a Brand Store on Amazon will automatically be enrolled in the Brand Follow feature. This solution allows customers to follow a brand on Amazon, ensuring they receive updates about new products, promotions, and other brand-related activities. By having a Brand Store, businesses can engage customers more directly, and the Brand Follow feature helps to keep customers informed and connected to the brand. While "Sponsored Brands" and "Posts" are both advertising solutions that can complement a Brand Store, they do not automatically enroll businesses that have a Brand Store like "Brand Follow" does.
