Correct Option: C. To ensure that the total of individual account balances matches the general ledger Detailed Explanation: Control accounts are a crucial component of the accounting system, particularly in the context of managing accounts receivable and accounts payable. The primary purpose of control accounts is to provide a summary of the total balances of individual accounts, ensuring that these totals match the corresponding balances in the general ledger. Here’s a step-by-step breakdown of why option C is correct:

1. Definition of Control Accounts: Control accounts are summary accounts in the general ledger that consolidate the total balances of a group of related accounts. For example, the accounts receivable control account summarizes all individual customer accounts, while the accounts payable control account summarizes all individual supplier accounts.
2. Reconciliation: The main function of control accounts is to facilitate reconciliation. By comparing the total balance in the control account with the sum of the individual accounts, accountants can quickly identify discrepancies. This process helps ensure the accuracy of financial records and reduces the risk of errors.
3. Error Detection: If the total of the individual accounts does not match the control account, it indicates that there may be errors in the recording of transactions. This could be due to data entry mistakes, missing transactions, or incorrect postings. Control accounts thus serve as a tool for internal control, helping to maintain the integrity of financial data.
4. Efficiency: Control accounts streamline the accounting process. Instead of reviewing each individual transaction, accountants can focus on the summary figures. This efficiency is particularly beneficial for businesses with a large number of transactions.
5. Financial Reporting: Control accounts provide a clear and concise way to present financial information in reports. Stakeholders can quickly assess the overall financial position of the company regarding receivables and payables without delving into the details of each transaction.

Why Other Options Are Incorrect:

• Option A: To provide a summary of individual transactions for each customer This option is incorrect because control accounts do not provide a detailed summary of individual transactions. Instead, they summarize the total balances of individual accounts. Individual transaction details are maintained in subsidiary ledgers, not in control accounts.
• Option B: To track the physical inventory levels of a company This option is also incorrect. Control accounts are not used for tracking physical inventory levels. Inventory management typically involves inventory accounts and systems that track stock levels, costs, and movements, which are separate from control accounts.
• Option D: To record cash transactions only This option is misleading. Control accounts are not limited to cash transactions; they encompass all transactions related to accounts receivable and accounts payable. Cash transactions are recorded in cash accounts, which are distinct from control accounts.

Summary of Key Points:

• Control accounts summarize the total balances of individual accounts, ensuring they match the general ledger.
• They facilitate reconciliation and help detect errors in financial records.
• Control accounts improve efficiency by allowing accountants to focus on summary figures rather than individual transactions.
• They are not used for tracking inventory or recording cash transactions specifically.

By understanding the role of control accounts, students can appreciate their importance in maintaining accurate and reliable financial records in accounting.
