A company is implementing a multi-locale solution that includes B2C Commerce, Service Cloud, and Marketing...

The shipping method name and description can be missing when order confirmation emails are triggered for languages other than US English, while other translated content appears correctly, for the following possible reasons:

The name and description for the shipping method are not set up correctly in B2C Commerce or Service Cloud for the requested locale. The shipping method name and description are stored as attributes in B2C Commerce or Service Cloud, and they need to be translated and localized for each supported locale. If the translation or localization is missing or incorrect, the order confirmation email may not display them properly.

The ShippingMethods data extension is missing the label and description field for the corresponding locale. The ShippingMethods data extension is a table in Marketing Cloud that stores the shipping method information for each locale. It has fields for label and description that need to match the values in B2C Commerce or Service Cloud. If the fields are missing or mismatched for a certain locale, the order confirmation email may not display them properly.

Option B is incorrect because the subscriber in Marketing Cloud does not need to have a preferred locale set. The locale can be determined by the order data or the storefront language. Option C is incorrect because the locale can be set correctly in the email template using AMPscript or SSJS variables. References:
