• C. Bowman's capsule
• D. Ureter

Answer 1

Answer: (B)

Minor calyx

The renal pelvis is made of two or three divisions called the major calyses. Each major calyx branches into several cup-shaped minor calyces. The apical portion called the papilla, of each renal pyramid projects into a minor calyx. The tip of the papilla is perforated with the openings of 10-25 papillary ducts, the final collecting ducts of the uriniferous tubules, and is therefore called the area cribrosa.

So, the correct answer is option B.
