Answer:
b. estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal, an allowance for an approximately normal profit margin, and an adequate reserve for possible future losses.

Thus, the "market" must not be more than the estimated selling price in the ordinary course of business, with an allowance for an approximately normal profit margin, and an adequate reserve for possible future losses.
