Which of the following represents cash sales expenditure?

The choice indicating the sales of surplus inventory accurately represents cash sales expenditure because it directly involves generating cash flow through the sale of items that the organization no longer needs. When surplus inventory is sold, the organization receives cash in exchange for these goods, thus contributing to its revenue stream. This transaction is categorized as an expenditure related to cash sales since it reflects an exchange that results in an immediate financial transaction where cash is collected from the buyer.

In contrast, requisitioning items from storage pertains to the internal movement of supplies and does not involve the generation of cash. The transfer of property between units indicates logistical movement but does not involve cash transactions. Meanwhile, a financial audit of assets is an accounting process focused on reviewing and evaluating financial records, without any immediate impact on cash flow. Each of these activities serves different purposes within the logistics and financial framework but does not equate to cash sales expenditure like the sales of surplus inventory does.
