c$.$ What is the reason for the difference in the amount of operating income 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 increases, the

income statement will have a higher operating income.
