Answer:
The correct answer is the option D: may allow sellers to increase sales volume.
Step-by-step explanation:
To begin with, the fact that sellers allow customers to use credit cards is because mainly it increases the ways that the clients can pay for the products and if those methods increase then the sales' volume will increase as well due to the fact that there is a direct relationship between the payment methods that the consumers have and the sales' volumen of the company. That is the major reason why a seller may allow the consumers to pay with credit card and to accept the risk of doing it.
