Correct answer
The alternator.
The alternator primarily generates electricity and recharges the battery. The thermostat regulates coolant flow and hoses carry it between circuit components. A duct cannot generically be excluded from every cooling system: it may carry air or liquid depending on design. This question concerns these components’ primary functions in a conventional system, rather than every cooling arrangement.
