Hello there!
Your question asks what answer choice best describes credit sales
Answer: Sales to customers on account
The reason why "Sales to customers on account" would be the correct answer because this specifically describes what a credit sale is.
Credit sales is a purchase that a customer made that the actual payment would be "delayed." This could also mean that they don't pay the whole thing at once. This means that a customer could buy a refrigerator, but instead of paying the whole price, they pay in parts until they completely pay off the refrigerator.
This could also be known as "financing." Since the customer is making a purchase without paying for the whole thing at once.
The customer would be "on account" because they would have to follow the "calculations" (payments) that they have to make in order to pay off the product they purchased.
I hope this helps!
