When setting up a product feed in the Google Merchant Center,which of the following attributes is optional?

The correct answer is product_type.When setting up a product feed in the Google Merchant Center,the attribute product_type is optional.While attributes like image_link,price,and availability are essential for ensuring that product listings are accurate and informative,theproduct_type attribute is not mandatory for creating a functional product feed.Product_typeis typically used to categorize products within the feed,providing additional organizational structure for product groups or for more specific ad targeting.However,its absence doesn'thin der the functionality of the feed or the performance of Shopping campaigns. Therefore,if a business is unsure about how to categorize its products or simply doesn't need this level of granularity in its feed structure,it can opt not to include the product_type attribute without affecting the overall functionality or performance of the feed in the Google Merchant Center.
