Match the formula to the financial phrase, where

n is the total number of compounding periods;

A. P[(1+r/n)^m -1]
B. P[e^(rn) - 1]
C. P [e^(rt) - 1]
D. P [(1 + r/m)^n - 1]
E. Prt
F. None of the above

A or B or C or D or E or F is compound interest
A or B or C or D or E or F is continuous compound interest
A or B or C or D or E or F is simple interest
