Which statement is Correct?

One of the common issues of IRR and MIRR is the possibility to have multiple rates.

As long as the NPV of a project is negative, the IRR is greater than the required return $($discount rate$).$

The payback period is always longer than the discounted payback period.

At the cross$-$over rate, two projects have the same IRR.

Profitability index provides a better measurement than the NPV to choose appropriate project$($s$).$

Cash flows of the farther years have more impact on the NPV of a project than the cash flows of the near years.
