Correct option is C
The correct answer is (c) sunk cost.
· A sunk cost is a cost that has already been incurred in the past and cannot be recovered, regardless of future actions or decisions.
· Sunk costs are irrelevant to current or future decision-making because they cannot be changed.
· This concept is important in economics and business because it encourages decision-makers to focus on potential future costs and benefits, rather than costs that cannot be altered.

· Prime cost: A term in cost accounting that includes direct costs of production, such as direct labor and raw materials, but does not include past incurred costs.
