A alternativa correta é a letra "d) III and IV are correct." pois os ímãs artificiais são aqueles que são feitos de materiais ferromagnéticos, como o ferro, e não são encontrados naturalmente na natureza, mas podem ser produzidos artificialmente. Além disso, os ímãs artificiais podem ser permanentes ou temporários, dependendo do material utilizado em sua fabricação.
