A alternativa correta é a letra D: "A força externa é aplicada no início da alavanca e a força interna é aplicada no final". Nesse caso, a alavanca tem um braço mais longo do lado da força aplicada, o que permite que uma força menor seja aplicada para levantar uma carga maior. Isso resulta em uma vantagem mecânica.
