Based on the following information, identify the three types of epithelial tissue in the figures given below:

(i) Cuboidal epithelium: It consists of a single layer of cuboidal cells.

(ii) Columnar epithelium: It is composed of tall, cylindrical cells with oval nuclei usually placed at the base of the cells.

(iii) Ciliated epithelium: It consists of cells bearing hair-like cilia on their free surface.

(a) …………..
