问题如下：
Which of the following most likely signals that a manufacturing company expects demand for its product to increase?
选项：
A.Finished goods inventory growth rate higher than the sales growth rate
B.Higher unit volumes of work in progress and raw material inventories
C.Substantially higher finished goods, with lower raw materials and work-in-process
解释：
B is correct.
A significant increase (attributable to increases in unit volume rather than increases in unit cost) in raw materials and/or work-in-progress inventories may signal that the company expects an increase in demand for its products. If the growth of finished goods inventories is greater than the growth of sales, it could indicate a decrease in demand and a decrease in future earnings. A substantial increase in finished goods inventories while raw materials and work-in-progress inventories are declining may signal a decrease in demand for the company’s products.
