The correct answer is (A). The walls of nephrons primarily consist of epithelial cells that carry out the various processes occurring in the kidney: filtration, reabsorption, and secretion. Connective tissue cannot carry out such processes, and nerve and muscle activities play no role in this aspect of urinary function.
