A project has a useful life of 6 years. The net present value (NPV) of the project is positive and the payback period (PB) is 3 years. If you change the cash flows by adding $1,000 in year 2 and subtracting $1,000 in year 4, then O A. the NPV will decrease and the PB will increase O B. the NPV and the PB will both decrease O C. the NPV and the PB will both increase OD. the NPV will increase and the PB will decrease
