The relationship equation of time value of money between final annuity and beginning annuity is as follows A、Present value or future value of beginning annuity ≥Present value or future value of final annuity×（1+r） B、Present value or future value of beginning annuity ≤Present value or future value of final annuity÷（1+r） C、Present value or future value of beginning annuity =Present value or future value of final annuity×（1+r） D、Present value or future value of beginning annuity =Present value or future value of final annuity÷（1+r）
