Answer 1

The correct option is D pseudostratified cells

Pseudostratified cells are simple, columnar epithelial cells in which the nuclei lie at different levels. This is due to the varying sizes of cells. Hence it appears to be multi-layered. It is seen in the goblet cells of the alimentary canal. Some pseudostratified cells such as the cells of the trachea also have cilia that move mucus and foreign particles towards the larynx.
