De acordo com a ABNT NBR 8160:1999, a altura mínima para a extremidade aberta da coluna de ventilação e do tubo de exaustão deve ser de 2 metros acima do terraço, no caso de uma laje utilizada para fins diferentes de cobertura. Além disso, a extremidade aberta da coluna de ventilação e do tubo de exaustão deve estar a uma altura mínima de 4 metros de qualquer janela, porta ou abertura de ventilação, a menos que seja elevada pelo menos 1 metro das bordas das respectivas aberturas. Portanto, a alternativa correta é a letra C) Ambos os itens estão corretos.
