Which of the following statments relating to relevance and controllability is not correct?

	A.	Using the concept of relevance can potentially reduce the number of costs and benefits to consider for the choice of optimal option.
	B.	While a relevant cost is always controllable, a controllable cost is not always relevant.
	C.	When using the principle of controllability to identify the incremental costs and benefits relative to the status quo, calculate the value of each option, and choose the one with the lowest value.
	D.	If the status quo is a feasible option, then all controllable costs and benefits are relevant.
