You are designing a SharePoint 2010 solution for a large sales force. You have the following requirements:
Each sales region must have its own site within the solution with lists to track the current sales data of the sales
executives.
.These lists must contain information about the status of sales opportunities, the estimated price, the expected
close date, and contact information for the potential sale.
.The welcome page for the root site must display a current summary for all regions, including the percentage of
sales expected to close within the next month and total expected revenue over time. You need to design the
solution to meet all these requirements. What approach should you recommend?

A.
Create site columns from the Managed Metadata Services feature within Central Administration to specify and display the sales information on the root site.

B.
Create an event receiver for each list to copy the list data when an item is inserted into a list on the root site.
Create a List View Web Part to display the sales information on the root site.

C.
Create a content type for the metadata to be tracked. Use a Content Query Web Part to display the sales information on the root site.

D.
Create a custom workflow to manage the list item data and update properties on the Web Part to display the sales information on the root site.
