What type of credit is represented by a monthly telephone bill?

The correct choice is single-payment credit. A monthly telephone bill represents an obligation to pay a specific amount for the service used during the billing period, typically due in full on a set date. This aligns with the characteristics of single-payment credit, where the total balance is paid off at once rather than in installments or through revolving credit.

In contrast, revolving credit allows for ongoing borrowing against a credit limit, where amounts can be carried over and paid down over time. Installment credit involves fixed payments over a specified term, such as a loan for a car or mortgage. Asset-based credit typically refers to loans secured by tangible assets, such as real estate or personal property. The nature of a monthly telephone bill does not fit into these categories, making single-payment credit the most appropriate classification.
