Which of the following payment types is NOT available in Magento EE v. 1.13?

The option indicating Gift Card Payment is the only one that is not available in Magento EE version 1.13. This version supports several payment methods, including Zero Subtotal Checkout, which allows for orders to be placed without charge; Bank Transfer Payment, which enables transactions via bank transfer; and PayPal Payment Solutions, offering various PayPal integration options for e-commerce.

However, Gift Card Payment functionality, while commonly anticipated in e-commerce platforms for promotional and customer loyalty purposes, is not included out-of-the-box in Magento EE 1.13. To implement gift card capabilities, custom solutions or additional extensions would need to be utilized. This distinction highlights the limitations of certain functionalities in specific Magento versions, emphasizing the need for users to consider extensions for additional features based on their business requirements.
