Answer:
D. Original cost.
Step-by-step explanation:
As we know that the inventory should be valued at lower of cost or market value. Also , the market value is the middle amount among the replacement cost, net realizable value, net realizable value - normal profit margin
It can be the replacement cost or net realizable value. We don't have an idea which one is the middle amount
Also, if the original cost is less than the market cost so we assume that the inventory should be valued at original cost
