The correct answer is: D. process costing system.
A process costing system is a type of costing system that is used to track the costs of production for a large number of identical or similar products. It is used in industries where the products are produced in a continuous process, such as the chemical, oil, and gas industries.
In a process costing system, the costs of production are accumulated by process or department, and then divided by the number of units produced to determine the cost per unit. This cost per unit is then used to value the inventory of work in process and finished goods.

- A sale costing system is a type of costing system that is used to track the costs of sales. It is used in industries where the products are sold individually, such as the retail industry.
- A job costing system is a type of costing system that is used to track the costs of individual jobs or projects. It is used in industries where the products are unique or custom-made, such as the construction industry.
- A price costing system is a type of costing system that is used to determine the price of a product. It is based on the costs of production, the desired profit margin, and the competitive market conditions.
