Expert Solution
Step 1

Correct answer is option B (PODOCYTES)

The outer wall of Bowman's capsule is composed of flattened squamous cells 

The inner invaginated wall that lines the concavity of Bowman's capsule is composed of a special type of cells called Podocytes, which are arranged in an intricate manner so as to leave some minute spaces called filtration slits or skit pores.

These cells are actually simple squamous cells and bear finger like projections which are coiled around the capillaries of glomerulus.
