Answer
(c) Renal pelvis.
The nephrons empty into COLLECTING DUCTS, which converge and discharge the urine into the RENAL PELVIS — the funnel-shaped cavity at the centre of the kidney where urine collects before passing into the ureter.
READ THE QUESTION CAREFULLY: it asks where the nephrons DISCHARGE, not where the urine eventually goes. The urinary bladder and urethra come much later in the path and are nowhere near a nephron.
The full route: NEPHRON → collecting duct → RENAL PELVIS → URETER → URINARY BLADDER → URETHRA → outside.
Option (d) RENAL PYRAMID is the near-miss: the pyramids are the cone-shaped regions of the medulla THROUGH which the collecting ducts run, and they point INTO the pelvis — but the discharge itself is into the pelvis.
