The best choice for the mucous membrane that lines the trachea would be A which mentions cilia and goblet cells. This is because cilia are important in trapping foreign particles and moving them out of the respiratory tract while goblet cells produce mucus that helps in trapping particles and preventing them from entering deeper into the respiratory system. Flagella are not present in the respiratory tract and serous cells and simple squamous epithelium are not the predominant cell types lining the trachea. Mucous cells and serous cells are both involved in producing and secreting mucus but do not accurately describe the specific cell types present in the tracheal mucous membrane.
