DCF Schedule Partial Period Adjustment

In practice, there are two different ways to calculate the terminal value in a DCF. Which of the following is NOT a formula that would work in order to calculate the partial period adjustment in a DCF? Assume dates are in row 9 in this hypothetical model. (Some numbers may be off slightly due to leap years and day-count conventions.)

a)=DAYS(I9,H9)/365

b)=YEARFRAC(I9,H9)

c) =(I9-H9)/365

d)=1-(I9-H9)/365
