you are using net present value profile to compare two projects. at the point where the net present value of the two project intersect the:

a. net present value of each project is equal to zero

b. internal rate of return is equal to the required rate of return

c. relevent discont rate is call the crossover rate

d. internal rate of return of each project is equal to zero

e. the accouting rate of return of each project is equal to zero
