B.
Create a Data Execution Prevention (DEP) exception.

C.

Explanation:
Windows XP Mode requires a processor that supports hardware virtualization using either the AMD-V or Intel VT options. Most processors have this option disabled by default; to enable it, you must do so from the computer�s BIOS. After the setting has been configured, it is necessary to turn the computer off completely. The setting is not enabled if you perform a warm reboot after configuring BIOS. As 256 MB of RAM must be allocated to the Windows XP Mode client, the computer running Windows 7 on which you deploy Windows XP Mode requires a minimum of 2 GB of RAM, which is more than the 1 GB of RAM Windows 7 hardware requirement.
