Solution

The correct option is D Afferent arteriole is slightly broader than efferent arteriole
The glomerulus is a tuft of capillaries formed by the afferent arteriole. The blood reaches the glomerulus via afferent arteriole and blood from the glomerulus is carried away by an efferent arteriole. The effective filtration pressure in the glomerulus is due to afferent arteriole is slightly broader than efferent arteriole.
So, the correct answer is 'Afferent arteriole is slightly broader than efferent arteriole'.
