2.

The app_custom_mystore cartridge contains any custom code for all other business functions.

3.

A. Set the cartridge path so that app_custom_newproject is before app_custom_mystore.

B. Set the cartridge path so that app_custom_newproject is between app_custom_mystore and app_storefront_base.

C. Set the cartridge path so that app_custom_mystore is before int_cybersource.
