This approach correctly addresses all requirements. Creating a Project report is the correct starting point. Adding the 'Actual Cost' column and sorting it in descending order fulfills the request to see the most expensive projects first. Most importantly, adding a prompt for 'Portfolio Name' from the Report Settings is the specific function that allows a user to select a single, specific portfolio each time the report is run. This makes the report reusable for any portfolio as requested by the executive.

B. Grouping and summarizing by SUM would show the total cost for all portfolios, not the individual project costs within a single, selected portfolio as requested.

C. Grouping by Portfolio Name displays all portfolios in the same report, which does not meet the requirement to select and view a single, specific portfolio.
