Northern Trail Outfitters is using a triggered send to send customers their order confirmations.

BuildRowSetFromJSON() is the AMPscript function documented by Salesforce specifically for parsing a JSON payload — such as an order-details object from a commerce platform — directly into an AMPscript rowset that can be looped through with RowCount() and Field() to render order line items, quantities, and prices inline in email content. Because AMPscript executes natively at send time within Content Builder emails, this is the correct, in-content mechanism for the scenario described. Option D, the SSJS platform function ParseJSON, is a real Marketing Cloud function, but it operates in server-side JavaScript context (used in Script Activities and CloudPages), not natively inside AMPscript-based email content — it is the wrong layer for formatting JSON directly within an email ' s AMPscript. Option A, ' ParseJSON content block within Content Builder, ' is not a real Content Builder block type; ParseJSON is a function, not a drag-and-drop content block. Option B, TransformJSON(), does not exist as an AMPscript or SSJS function in Marketing Cloud ' s documented function library and should be treated as a fabricated distractor. Consultants should default to BuildRowSetFromJSON() whenever the requirement is parsing and displaying JSON-structured order or product data directly within AMPscript email content.
