Which of the following is an optimal main image?

Option B is the optimal main image because it clearly showcases the product against a pure white background, filling at least 85% of the image frame, which aligns with Amazon's best practices for main images. The product is well-lit, in focus, and free of distracting elements like text, logos, or watermarks. Option A is incorrect because it includes a logo and lifestyle elements, which are not permitted for main images. Option C is incorrect because it shows multiple variations of the product and includes text overlays, both of which violate Amazon's main image guidelines.
