Assume that you graph the changes in net present value against the changes in the value of a single variable used in a project. The smoother the resulting function/line illustrates the

	a.	the higher the forecasting risk or sensitivity associated with that variable
	b.	the higher the fixed costs utilized by the project
	c.	the less sensitive NPV is to change in that variable
	d.	the wider the range of total outcomes possible from accepting a proposed project
