What is true about process costing?

Process costing is a method used to allocate costs to products that are produced in a continuous flow, often in large batches. This approach is particularly beneficial when the work performed on each product is uniform and similar, which corresponds directly to the essence of option C. When products are produced through various work centers and the processes or treatments they undergo are consistent, process costing allows for an equal distribution of costs across all units produced. This smooth allocation is essential for accurately determining the cost per unit in manufacturing environments where products are homogeneous.

In contrast, the other options contain inaccuracies regarding the nature and applicability of process costing. For instance, the ability to apply specific product costs is more aligned with job order costing, which is designed for individual items or unique orders. Additionally, while process costing is prevalent in manufacturing, it can also apply to service firms that offer homogeneous services, making the claim in another option too restrictive. Finally, asserting that process costing is always more accurate than job order costing ignores the context-dependent nature of cost allocation methods. The appropriateness of a costing method is determined by the production environment, not an inherent superiority of one method over the other.
