What property must be checked for a product to be orderable?

To determine whether a product is orderable, the most relevant property to check is the orderable property. This property specifically defines whether a product can actually be purchased or added to a customer's order. When a product has the orderable property enabled, it signifies that it is available for customers to select and place into their shopping cart or order.

The properties described in the other options play important roles in the overall management and presentation of products, but they do not directly influence a product's orderability. The active property indicates whether the product is currently available in the system, while the visible property pertains to whether the product can be seen by the user. The price property, on the other hand, ensures that a product has a defined cost. However, having a price or being visible does not necessarily mean the product is orderable if it lacks the orderable property. Therefore, confirming that the orderable property is checked is essential for a product to be successfully added to an order.
