You are a desktop support technician for your company. All client computers run Windows XP Professional.

A user reports that macros that previously worked in Microsoft Excel do not run after she installed Windows XP Service Pack 2 (SP2). The user receives the following error message: ???Macros in this workbook are disabled because the security level is high, and the macros have not been digitally signed or verified as safe. To run the macros, you can either have them signed or change your security level. Click Help for more information.???

The user wants to configure Excel to automatically run macros that are included in spreadsheets.

What should you instruct the user to do?

A.
In Excel, on the Tools menu, click Options. On the Security tab, click Macros Security, and then set the macro security level to Low.

B.
In Excel, on the Tools menu, click Options. On the Security tab, click Macros Security, and then set the macro security level to Medium.

C.
In Excel, on the File menu, click Permission, and then select Unrestricted Access.

D.
In Excel, on the Tools menu, click Protection, and then select Allow users to edit ranges.
