C. Line Item has a re-parentable master-detail field to Order.
1. Calculate the total amount on an Order: This is best achieved using a master-detail relationship where the parent record (Order) can have roll-up summary fields that sum up values from child records (Line Items).
2. Calculate the line amount for each Line Item based on quantity selected and price: This can be handled within each Line Item record and doesn’t necessarily depend on the relationship type.
3. Move Line Items to a different Order if a Line Item is not in stock: This requires that the Line Item be re-parentable, meaning the relationship should support changing the parent record.
