Google: compound interest

Then its A right

Yes, A.

Yes, the correct answer is D. Compound interest refers to the interest paid on both the principal amount and any accumulated interest from previous periods. This means that the interest not only accumulates on the initial amount deposited or borrowed (principal), but also on the interest earned or charged over time. Therefore, compound interest is not limited to just the principal amount.
