Last-in, First-out (LIFO) is just the opposite of FIFO. Under the last-in, first-out (LIFO) method, ending inventory comes from the oldest costs (beginning inventory and earliest purchases) of the period.

This method is forbidden for being misleading especially in hyper-inflationary economies. The correct answer is B.
