Universal Containers (UC) uses Salesforce for tracking opportunities (Opportunity). UC uses an internal ERP system for tracking deliveries and invoicing. The ERP system supports SOAP API and OData for bi-directional integration between Salesforce and the ERP system. UC has about one million opportunities. For each opportunity, UC sends 12 invoices, one per month. UC sales reps have requirements to view current invoice status and invoice amount from the opportunity page. When creating an object to model invoices, what should the architect recommend, considering performance and data storage space?

A. Create an external object Invoice _x with a Lookup relationship with Opportunity.

B. Create a custom object Invoice _c with a master -detail relationship with Opportunity.

C. Use Streaming API to get the current status from the ERP and display on the Opportunity page.

D. Create a custom object Invoice _c with a Lookup relationship with Opportunity.
