The relationship equation of time value of money between final annuity and beginning annuity is as follows

A、Presentvalueorfuturevalueofbeginningannuity≥Presentvalueorfuturevalueoffinalannuity×（1+r）;
B、Presentvalueorfuturevalueofbeginningannuity≤Presentvalueorfuturevalueoffinalannuity÷（1+r）;
C、Presentvalueorfuturevalueofbeginningannuity=Presentvalueorfuturevalueoffinalannuity×（1+r）;
D、Presentvalueorfuturevalueofbeginningannuity=Presentvalueorfuturevalueoffinalannuity÷（1+r）
