Fabian is checking his client's product detail page for retail readiness. Which of the following issues should he flag as needing improvement to be considered retail ready?

Having only 5 items left in stock is a critical retail readiness issue because low inventory can lead to products being unavailable for purchase, resulting in lost sales and a poor customer experience. Amazon prioritizes products with consistent availability. While a 4-star rating, 15 customer reviews, and enhanced content with a video are all positive attributes that contribute to a strong product detail page, they do not directly impact the immediate ability to fulfill orders. Retail readiness primarily focuses on ensuring a product can be consistently purchased and delivered to customers.
