A sunk cost is a cost that has already been incurred and cannot be recovered. The accumulated depreciation of $90,000 on the old machine is a sunk cost, and since it is not listed as an option, the closest related figure is the net book value of the old machine, which is $210,000 ($300,000 - $90,000).
