Choice-’A’ is the one that describes compound interest.

’A’ is the value of the account after some time.

’P’ is the ’principle’. the amount you originally put in, before any interest.

’r’ is the interest rate

’n’ is the number of times per year that interest is paid

’t’ is the number of interest payments that have happened
since you first put the money in the bank.

The answer should be A as it best satisfies the equation of compound interest

; where A is the value of account, P is principle, r is rate, n is frequency of interest payments per year and t is time.
