Answer:
Cost of direct labor goes up if flow rate goes up
Step-by-step explanation:
As we know that
Cost of direct labor = Wages per unit of time ÷ Flow Rate
This cost of direct labor implies that whenever the flow rate rises, the cost of direct labor will decline that depicts the negative relationship between them and if the flow rate declines, the cost of direct labor increases
Moreover, by dividing the wages per unit of time from the flow rate we can get the cost of direct labor
Therefore, the first option is correct that shows the given statement is false regarding the process efficiency
