Answer:
B
Step-by-step explanation:
Nearly all the decisions that doesn't result in true or falls are marginal decisions. For example turning on a light or not is not a marginal decision because it only results in true or false. whereas choosing how many lights to turn on is a marginal decision because we can choose number of lights that needs to be turned on.
That is why hiring new workers is marginal decision. Because we can choose between 1 or more employee to hire.
