A remoção da vegetação natural e dos primeiros centímetros do solo antes do início do processo de terraplanagem tem como objetivo remover a matéria orgânica presente no solo, que se deteriora ao longo do tempo, comprometendo a capacidade de carga do solo. Além disso, a remoção da vegetação e do solo superficial também permite a melhoria do solo, tornando-o mais adequado para a construção de aterros. Portanto, a alternativa correta é a letra B) As afirmações I e II estão corretas.
