The correct answer is A. Inventory subsidiary.
A master file is a file that contains permanent data about a company’s operations. It is used to store information about customers, products, vendors, and other important entities. The inventory subsidiary file is a master file that contains information about a company’s inventory, such as the quantity of each item on hand, the cost of each item, and the date of purchase. This information is used to track inventory levels, calculate costs, and generate reports.
The other options are not master files. Cash disbursements is a journal entry that records the payment of an expense. Cash receipts is a journal entry that records the receipt of cash. Payroll transactions are the records of employees’ earnings, deductions, and withholdings.
