Final answer:
The bank deposit is not part of the horizontal information flows in the B/AR/CR process.
Step-by-step explanation:
The correct answer is c. bank deposit.
The B/AR/CR process stands for Billing/Accounts Receivable/Cash Receipts process, which is a cycle that includes various steps related to billing customers, tracking accounts receivable, and processing cash receipts. In this process, horizontal information flows refer to the movement of information between different components or steps of the process.
Out of the options provided, bank deposit does not involve the movement of information. It is a physical deposit of cash or checks made by the company into its bank account. The other options, such as accounts receivable aging report, customer payment, and customer invoice, all involve the exchange of information related to billing, payment, and tracking of accounts receivable between different parties or documents.
