You are a database administrator for your company. A user named Susan belongs to the Windows SalesManagers group. Susan needs a Reporting Services report to display annual sales information by territory. A user named Joe reports to Susan and belongs to the Windows Sales group. He needs a report that is limited to his sales territory， but still displays the same detailed sales data that is on Susan’s report. You need to design a secure solution that meets the reporting needs of the users and that consumes the minimal amount of server resources. 
What should you do？（）

A . Design a report for Susan that includes two data regions. One data region is used for summary sales data. The other data region is used for the detailed sales data for each sales representative. Then， design a report for Joe that displays the detailed sales data.

C . Design a report for Susan that includes the territory information. Then， design a report for Joe that includes detailed sales data for his territories. Finally， configure Susans report so that it includes the data in Joes report.
