Final answer:
The correct syntax for a Liquid object with a metafield is C) {{ product.metafields }}. To access a specific metafield, you would use the syntax {{ product.metafields.namespace.key }}.
Step-by-step explanation:
The typical syntax for accessing a metafield of a Liquid object would be C) {{ product.metafields }}. In this syntax, 'product' is the Liquid object, and 'metafields' is the method for accessing its metafield data. When you want to get more specific, you can use namespacing and a key to access a particular metafield, for example, {{ product.metafields.namespace.key }}. Remember that metafields store additional information for products, collections, orders, blogs, pages, and your shop in Shopify and other platforms that utilize Liquid templating language.
