Which Liquid object can you use to access product information?

The correct choice, "all_products," is a Liquid object that provides access to detailed information about every product in a Shopify store. This object allows developers to look up specific products by their handles or IDs and access various attributes such as title, price, variants, images, and more.

Using "all_products" is particularly powerful because it enables you to retrieve data about products that may not be currently in the collection context, meaning you can access any product, regardless of whether it is a part of the currently displayed collection or not. This is crucial for dynamic scenarios where you want to show related products, upsells, or product comparisons.

The other options, while they might suggest a function related to product information, do not accurately represent the method used in Shopify's Liquid templating language to retrieve product data. For instance, "products_info" and "display_products" are not standard Liquid objects in Shopify, while "products_json" does not provide direct access to product information in a format usable within Liquid templates. Instead, developers typically prefer "all_products" for its comprehensive capabilities in accessing the store's product data.
