How can you adjust the cart layout to hide the Quantity field for a specific Catalog Item?

The option that involves adjusting the Catalog Item in the Advanced View by unselecting the "Use cart layout" and selecting "No quantity" is the correct way to hide the Quantity field for a specific Catalog Item. This approach allows for more granular control over how individual items are displayed in the cart, enabling the catalog administrator to configure item-specific settings rather than applying a broader change at the layout level.

By using the Advanced View, the user can modify settings that pertain specifically to that Catalog Item while leaving the general cart layout intact for other items. This is particularly useful when certain items may not require a Quantity field, such as services that are typically offered as one-time offerings or items where the quantity should not be modified during the checkout process.

Other choices may involve altering layout options or global settings that do not provide the same level of specificity for individual catalog items. As a result, these options would not effectively hide the Quantity field for a specific Catalog Item as intended.
