Which Azure component processes customer orders in the described order processing system?

In an order processing system, the component responsible for processing customer orders is typically an application that handles the business logic associated with order management. This includes receiving customer order requests, validating them, interacting with other services or databases as necessary, and providing feedback to the user or updating order statuses.

Choosing App1 as the appropriate component suggests that it serves as the main application where these transactions and workflows are executed. It likely encompasses functionalities that allow for order processing, including managing inventory, updating records, and possibly interfacing with payment systems. In contrast, the other options, such as Function1, Function2, and storage2, might represent specific functions or services but do not embody the comprehensive role that an application like App1 plays in handling the entire order processing flow.

This reasoning reinforces the role of a dedicated application component for processing orders, making App1 the most suitable choice in the context provided.
