What will you call the amount of money borrowed or invested?A.InterestB.Time periodC.LoanD.Principal

The correct answer is D. Principal.

Explanation: The amount of money borrowed or invested is called the "principal." This is the initial sum of money that is either borrowed from a lender or invested in an account or investment vehicle.

Let's break down the other options:

A. Interest: Interest is the extra money paid or earned on the principal amount. It is the cost of borrowing money or the return on an investment.
B. Time period: This refers to the length of time for which the money is borrowed or invested.
C. Loan: A loan refers to the actual borrowing agreement where a lender provides the principal amount to a borrower, who is then expected to repay it with interest.
So, the principal is the initial amount, and it is separate from interest, time period, or the loan agreement itself.
