Correct answer: C — Where the distal tubule contacts the afferent and efferent arterioles of its own glomerulus

The best answer is “Where the distal tubule contacts the afferent and efferent arterioles of its own glomerulus”. The macula densa segment of the distal nephron lies adjacent to the vascular pole of its own glomerulus, close to the afferent and efferent arterioles. Together with renin-secreting granular cells and extraglomerular mesangial cells, it forms the juxtaglomerular apparatus that coordinates tubuloglomerular feedback and renin release.
