Correct: D — the arterial supply to the adrenal comes from three sources. The superior suprarenal artery arises from the inferior phrenic, the middle directly from the aorta and the inferior from the renal artery — an arrangement of practical importance in adrenalectomy. The other options are wrong: the cortex is of mesodermal origin while the medulla derives from neural crest, so the gland does not share a single origin with the kidney (option A); the cortex has *three* zones, glomerulosa, fasciculata and reticularis (option B); and it is the *left* adrenal vein that drains into the renal vein, the right draining directly and shortly into the inferior vena cava — the anatomical fact that makes right adrenalectomy the more hazardous (option C).
