c. the cash flows for an ordinary (or deferred) annuity all occur at the beginning of the periods.
d. the cash flows for an annuity must all be equal, and they must occur at regular intervals, such as once a year or once a month. if some cash flows occur at the beginning of the periods while others occur at the ends, then we have what the textbook defines as a variable annuity.
