The correct answer is: A. Interest
Interest is the amount of money paid for the use of borrowed capital. It is usually calculated as a percentage of the principal amount borrowed, and is paid over a period of time. The interest rate is the percentage of the principal amount that is paid as interest each year. Simple interest is the amount of interest paid on the principal amount only, while compound interest is the amount of interest paid on the principal amount plus any interest that has already been earned.
