Final answer:
The correct option for the collection of documents in a work-in-process inventory file is 'c. job cost sheets'. The correct answer is option c.
Step-by-step explanation:
The question pertains to the components that make up a work-in-process (WIP) inventory file in the context of managerial accounting and cost accounting within a manufacturing environment. The work-in-process inventory file is a collection of detailed information regarding the costs associated with the production of goods that are not yet completed. The correct option from the provided choices is: c. job cost sheets.
Job cost sheets are documents that record and accumulate all the costs related to a specific job or production order. These sheets typically include direct labor, direct materials, and allocated overhead costs. In contrast, time tickets track the amount of time employees spend on specific jobs, material requisition forms document requests for issuing materials to the production floor, and purchase requisition forms initiate the procurement process of materials.
However, it is the job cost sheets that compile these details to report on the status and costs of ongoing work in the production process, hence they are the documents that make up the WIP inventory file.
