What is your recommendation to address this internal control issue, if the existing practice is of any concern? Select one: a. The bookkeeper should approve all new hires and payroll is to be deposited directly into employees' bank accounts. b. A new bookkeeper should be hired. The manager should be responsible for staff schedules and regular review of payroll costs as a consistent percentage of sales. O c. daily. Any discrepancies between the cash receipts and sales are investigated by the manager immediately. d. A new bookkeeper should be hired.
