Answer:
C. Recorded using a Create Invoices window
Explanation:
Credit sales refers to the purchases made by customers for which payment is delayed. A reasonable payment delay allows customers to make additional purchases as delayed payments allow customers to generate cash with the purchased goods which in turn can be used to pay back the seller.
These are purchases made by a customer that do not require a full payment  at the time of purchase.
Credit sales to customers are recorded using a Create Invoices window.
