One Difference Between IFRS and GAAP in Valuing Inventories Is

One difference between IFRS and GAAP in valuing inventories is that:

A) IFRS, but not GAAP, allows reversals so that inventories written down under lower-of-cost-or-market can be written back up to the original cost.
B) GAAP defines market value as replacement cost where IFRS defines market as the selling price.
C) GAAP strictly adheres to the historical cost concept and does not allow for write-downs of inventory values while IFRS embraces fair value.
D) IFRS, but not GAAP, requires that inventories be valued at the lower of cost or market.
