Answer 1

Answer: (C)

a) Squamous cells are thin and flat similar to the plate. Also, they form the lining of cavities such as the mouth, blood vessels, heart, and lungs. So, the option 'a' matches with option '4'.

b) Cuboidal cells are roughly square or cuboidal in shape. They are found in glands and in the lining of the kidney tubules and constitute the germinal epithelium, which produces the egg cells in the female ovary and the sperm cells in the male testes. So, option 'b' matches with option '3'.

c) Columnar epithelial cells are elongated and column-shaped. They form the lining of the stomach and the intestines. So, option 'c' matches with option '1'.

d) Ciliated epithelium consists of simple columnar cells but possesses fine hair-like cilia on their free surfaces. These cells are found in air passages like the nose, trachea, and in the uterus and Fallopian tubes of females. So, the option' matches with '2'.

e) Bronchioles carry air from the bronchi to the terminal bronchioles and are lined by ciliated pseudostratified columnar epithelium. So, option 'e' matches with option '5'.

Hence, the correct answer is option C.
