The correct answer is: Job costing.
Job costing is a type of costing that is used to track the costs of individual jobs or projects. It is a detailed costing method that takes into account the direct costs of each job, as well as the indirect costs that are allocated to the job.
Marginal costing is a type of costing that is used to determine the contribution margin of a product or service. It is a simpler costing method that only takes into account the variable costs of a product or service.
Batch costing is a type of costing that is used to track the costs of a batch of products or services. It is a less detailed costing method than job costing, but it is more accurate than marginal costing.
Multiple costing is a type of costing that is used to track the costs of multiple products or services. It is a more complex costing method than job costing, batch costing, or marginal costing.
