The correct answer is A. Distribution service.
Service costing is a method of accounting that tracks the costs of providing services. It is used by businesses to determine the profitability of their services and to make decisions about pricing, marketing, and operations.
Distribution services are typically not well-suited for service costing because they are difficult to track. The costs of providing distribution services are often indirect and difficult to allocate to specific services. Additionally, the prices of distribution services are often based on factors other than cost, such as volume or customer demand.
Hospitals, maintenance divisions of manufacturing companies, and light engineering companies are all businesses that provide services. However, the costs of providing these services are more easily tracked than the costs of providing distribution services. Additionally, the prices of these services are often based on cost, which makes service costing more useful for these businesses.
In conclusion, A. Distribution service is the correct answer to the question.
