20) The principal of optimization at the margin states that:

A) an optimal alternative has the least indirect costs in comparison to other feasible alternatives.

B) an optimal alternative has the highest net benefits in comparison to other feasible alternatives.

C) moving toward the optimal alternative makes the decision maker better off, and moving away from it makes him worse off.

D) moving toward the optimal alternative makes the decision maker worse off, and moving away from it, makes the decision maker better off.
