• C. A - Cuboidal epithelium, ducts of glands, secretion and absorption
• D. C - Columnar epithelium, lining of stomach, secretion and absorption

Answer 1

The correct option is D C - Columnar epithelium, lining of stomach, secretion and absorption

• The given figure A is squamous epitheliuth, found in the walls of blood vessels and air sacs of lungs and is involved in functions like forming a diffusion layer.
• B is cuboidal epithelium, found in ducts of glands and tubular parts of nephrons of kidney and its . main functions are secretion and absorption.
• C is columnar epithelium; found in lining of stomach and intestine and helps in secretion and absorption.
• D is ciliated columnar epithelium, present in inner surface of hollow organs like bronchioles and Fallopian tubes and helps move particles or mucus in a specific direction over the epithelium.
