A conglomerate is designing a Lightning Web Component (LWC) to display transactions aggregated from different sources. Their current system landscape is as follows:
1. Transactions are created at any time through their various on-premise and cloud-based systems.
2. All necessary transactions are replicated to a custom Transaction object in Salesforce. It is updated periodically so it only has a subset of the necessary transactions between updates.
3. Middleware supports publish-subscribe interactions and provides RESTful Enterprise APIs that can retrieve transactions from on-premise and cloud-based systems.
The company wants to address a usability concern regarding incomplete data displayed on the LWC component. What should the Integration Architect specify so the LWC will be able to display all the required transactions?

• A.Publish a Platform Event, have the middleware subscribe and update the custom object on receipt of Platform Event.
• B.Call the Enterprise APIs directly from the LWC's JavaScript code and redisplay the LWC on receipt of the API response.
• C.Let the Lightning Data Service with an ©wire adapter display new values when the custom object records change.
• D.Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.
