Answer:
b. Present Value Index
Explanation:
Present Value Index (PVI) is the ratio of net present value of a project, to the initial outlay needed for it. Net Present value (NPV) refers to expected income inflow from a project in different time periods, adjusted to discount rate between the current & further time period.
So, to compare 2 investment projects, investment A & investment B: It needs to compute NPV of expected inflows - per unit investment expenditure, i.e PVI. The investment option having higher Present Value Index [PVI], i.e net present value per unit investment expenditure, should be chosen.
