After conducting Monte Carlo Simulation you notice a very wide distribution of potential NPVs for a project. What does that usually mean?

a. The projects value is not sensitive at all to the underlying assumptions

b. Monte Carlo Simulation does not account for the time value of money and so is typically not a useful tool

c. Monte Carlo Simulation does not allow for uncertainty in your assumptions and so is typically not a useful tool

d. The projects value is very sensitive to the underlying
