Which of the following is true about perpetuities?
a. Since a perpetuity generates cash flows every period infinitely, the cash flow generated equals the PV times the interest rate.
b. Since a perpetuity generates cash flows every period infinitely, initial cash outflow must be discounted to calculate the present value.
c. Since a perpetuity generates cash flows every period infinitely, there is no way to solve for the cash flow using the present value and the interest rate.
d. Since a perpetuity generates cash flows every period infinitely, its future value is as same as its present value.
