Financial models are useful in ensuring that selected projects make sense from both cost and return$-$on$-$investment perspectives. Nonetheless, we must understand the weaknesses of these models before they are used. Which of these is NOT a weakness or disadvantage of using a financial model for project evaluation and selection?

a$.$ Payback period $($PP$)$ models do not consider the amount of profit that may be generated after the costs are paid.

b$.$ BCR $($benefit$-$cost ratio$)$ does not account for intangible benefits and costs that cannot be determined in financial terms.

c$.$ Internal rate of return $($IRR$)$ can favor smaller projects that create less total value for the firm but have high percentage returns.

d$.$ Use of financial models can ensure that selected projects make sense from both cost and return$-$on$-$investment perspectives.
