The correct answer is C. cement.
Process costing is a type of accounting that is used to track the costs of production in a process industry. It is used in industries that produce a large number of identical or similar products, such as chemical, oil refining, and food processing.
Cement is a product that is made by combining limestone, clay, and sand. It is a heterogeneous mixture, which means that it is not made up of identical or similar particles. This makes it difficult to track the costs of production using process costing.
In contrast, the other options (A, B, and D) are all industries that produce a large number of identical or similar products. This makes it easier to track the costs of production using process costing.
Here is a brief explanation of each option:
- A. Chemical: The chemical industry is a process industry that produces a wide variety of chemicals, including acids, bases, and solvents. Process costing is used to track the costs of production in the chemical industry.
- B. Textiles: The textile industry is a process industry that produces fabrics, such as cotton, wool, and synthetic fibers. Process costing is used to track the costs of production in the textile industry.
- D. Oil refining: The oil refining industry is a process industry that produces gasoline, diesel fuel, and other petroleum products. Process costing is used to track the costs of production in the oil refining industry.
