Which of the following is an example of a violation of usury laws?

Charging 25% interest on a loan is an example of a violation of usury laws because it exceeds the maximum interest rate allowed by state legislation. Usury laws are designed to protect consumers by preventing lenders from charging excessively high-interest rates that may be predatory or exploitative. Each state has its regulations regarding the maximum legal interest rate, and when a lender charges significantly above this limit, it constitutes usury.

In this context, options that involve no interest or interest rates below the established limits do not violate usury laws, as they either comply with legal standards or do not impose an unfair burden on the borrower. Thus, charging an interest rate like 25% crosses that legal threshold, highlighting the significance and enforcement of usury laws in lending practices.
