Solution

The correct option is C Brush bordered cubical
The luminal surface of the epithelial cells of the proximal convoluted tubule of the nephron is covered with densely packed microvilli forming a border readily visible under the light microscope giving the brush border cell its name. The microvilli greatly increase the luminal surface area of the cells, facilitating their resorptive function.
