Explanation:

In Salesforce B2C Commerce (SFCC), several conditions must be met for a product to appear in the storefront (search results, category listings, PDPs, etc.). If a product is missing, these are commonly overlooked reasons.

✅ D. Product Available to sell is <1
✔️ Correct
If ATS (Available To Sell) = 0 (or < 1), and the site is configured to hide out-of-stock products, the product won’t show.
This is managed via inventory settings and may vary per site or per configuration in:
Business Manager → Merchant Tools → Inventory
Or via storefront logic (SFRA)
➡️ Solution: Increase inventory or allow backorders/display out-of-stock products.

✅E. Product is not online
✔️ Correct
If the product is not marked as Online, it will not be visible in the storefront at all.
This setting is found under:
Business Manager → Merchant Tools → Products and Catalogs → Products
Then toggle the "Online" checkbox.
➡️ Solution: Set the product status to online.

❌ Why the Other Options Are Incorrect:
A. Product has been set to searchable ❌
Being searchable helps products appear in search results, but it does not hide products if they are set as searchable.
A product that is searchable can still be unavailable if other key visibility rules are not met (e.g., not online, out of stock).

B. Product lacks a price ❌
In SFRA, a product without a price can still be shown, though some functionality (like Add to Cart) might be restricted.
Some storefronts display “Call for price” or hide the price instead — but the product still shows up.

C. Product does not have any images ❌
A missing image does not prevent the product from showing in the storefront.
It might look incomplete or unappealing, but it will still appear unless explicitly filtered out via custom logic.
