c) Renal artery > Interlobar
artery > Interlobular artery > Arcuate artery > Afferent arteriole
d) Renal artery > Interlobar
artery> Arcuate artery > Interlobular artery> Afferent arteriole
Correct Answer: d
Explanation:
Renal artery gives off Interlobar
arteries which run between the pyramids of medulla. Interlobar arteries give
off arcuate arteries which run parallel to the junction of cortex and medulla.
Arcuate arteries give Interlobular branches into the cortex which in turn give rise
to the afferent arterioles.
