c. What is the reason for the difference in the amount of income from operations reported in (a) and (b)?

Under the method, the fixed manufacturing cost included in the cost of goods sold is matched with the revenues. Under , all of the fixed manufacturing cost is deducted in the period in which it is incurred, regardless of the amount of inventory change. Thus, when inventory decreases, the income statement will have a lower income from operations.
