Please show the steps(formulas) of calculation

Consider the following two projects: Suppose you are currently planning project Alpha. You are considering giving up project Alpha and undertaking project Kappa instead. Be VERY careful to first analyse the above cash flows before choosing an appropriate best decision making criteria from below. A. Calculate the incremental internal rate of return (on Kappa minus Alpha), and switch if this incremental internal rate is greater than 15% B. Calculate the incremental internal rate of return (on Kappa minus Alpha), and switch if this incremental internal rate is less than 15%. C. Calculate the NPV of Alpha minus the NPV of Kappa, and switch if the difference is greater than 0. D. Calculate the NPV of Kappa minus the NPV of Alpha, and switch if the difference is less than 0. E. None of the above
