For a list report that includes columns for purchase requests and regional cost centers, and with a requirement to show the total number of purchase requests for each regional cost center, the correct approach is to summarize the relevant data in a way that aligns with the manager's needs.
* C. Summarize the purchase requests column by count: This configuration aggregates the purchase requests data, providing a count of purchase requests per cost center. It effectively meets the manager's requirement by offering a clear and concise summary of the total number of purchase requests for each regional cost center, facilitating easy analysis and decision-making.

* A. Verify the data page has the correct item prices: This test ensures that the prices pulled from the external inventory management system into the application via the data page are accurate. Correct item pricing is foundational to calculating the total cost for items in the shopping cart.
* D. Verify the order total cost property is accurately calculated: This test checks whether the application correctly calculates the total cost of all items in the shopping cart, considering both the individual item prices and their quantities. Accurate total cost calculation is crucial for the final order summary and checkout process.
Verifying the data transform copies the correct value (B) is important for data integrity but is a more granular detail compared to the overarching need to ensure accurate pricing and total calculations. Verifying the price fields are displayed in the correct format (C) is also significant but focuses more on UI presentation than on the underlying functional correctness of pricing and total cost calculations.
