Final answer:
Simple cuboidal epithelium is cube-shaped tissue involved in secretion and absorption and is specifically found in the kidney tubules where it assists in filtering blood.option d is correct.
Step-by-step explanation:
Simple cuboidal epithelium is a type of tissue composed of cube-shaped cells with a central nucleus. This epithelial tissue has a specific role in secretion and absorption, and is commonly found in glandular tissues and the renal system. Characteristically, it lines structures such as the walls of the kidney tubules and ducts of glands, where it is integral in filtering blood and preparing glandular material.
Considering the available options in the question, the simple cuboidal epithelium is not found at the surface of the skin, in the trachea, or lining blood vessels or air sacs of the lungs. Instead, it falls under option d) forming the kidney tubules, where it plays a crucial role in the filtration and reabsorption processes necessary for kidney function. Therefore, the correct answer to the question is: d) forming the kidney tubules.
