Having some trouble with this question. Would really appreciate any help. Thank you!

If a firm discovers a ranking conflict exists after evaluating two mutually exclusive capital budgeting projects using the net present value (NPV) technique and the internal rate of return (IRR) technique, which of the following capital budgeting techniques should it use to ensure the correct value-maximizing decision is made?

Traditional payback period (PB)

Net present value (NPV)

Internal rate of return (IRR)

Discounted payback period (DPB)

It doesn't matter which capital budgeting technique is used because they all produce correct value-maximizing decisions.
