Solution
The correct option is A Proximal convoluted tubule
Proximal convoluted tubule – It is lined by simple cuboidal epithelium. The cuboidal epithelium is composed of a single layer of cube-like cells. This is commonly found in ducts of glands and tubular parts of nephrons in kidneys, and its main functions are secretion and absorption. The epithelium of proximal convoluted tubule (PCT) of nephron in the kidney has microvilli.
Olfactory epithelium - The epithelium is a pseudostratified columnar specialized region of tissue lining the nasal cavities that contain olfactory receptor cells.
Lung alveoli - The squamous epithelium is made of a single thin layer of flattened cells with irregular boundaries. They are found in the walls of blood vessels and air sacs (alveoli) of lungs and are involved in functions like forming a diffusion boundary.
Inner layer of Bowman’s capsule - It is lined by simple squamous epithelial tissue. The inner or visceral surface contains specialized cells called podocytes that form slit-like structures to facilitate filtration.
