Final answer:
In a strong system of internal control, the manager is the appropriate employee to verify cash count sheets, prepare deposit slips, and transport cash to the bank, as this maintains separation of duties and provides oversight.
Step-by-step explanation:
In a strong system of internal control, the responsibility to verify cash count sheets, prepare deposit slips, and take the cash to the bank would ideally be divided among different employees to maintain a system of checks and balances. However, when the question presents specific roles, the manager is typically the best choice from the provided options. The manager would have the authority to oversee the cashier, who handles cash transactions, and the accountant, who records the transactions. By involving the manager in the verification and banking process, the system maintains separation of duties, which is a fundamental principle of a robust internal control system. The security guard, while responsible for the physical security of the premises, would not typically be involved in financial procedures such as verifying cash or preparing bank deposits.
