- B. Squamous epithelium
- C. Columnar epithelium

Explanation
Squamous epithelium is a type of tissue composed of flat, scale-like cells. It forms the outer layer of the skin (epidermis) and lines the body cavities and blood vessels. When a frog is kept in water for some time, the outer layer of its skin may undergo a process called sloughing or shedding. This process involves the shedding of the squamous epithelium to remove old or damaged skin.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
