• C. Are less and more respectively
• D. Depending on working capacity of arteriole

Answer 1

The correct option is B Are more and less respectively

In healthy person the diameter of afferent arteriole is bigger than efferent arteriole to produce an extraordinary force of blood in the glomerulus which directly contributes in the efficiency of ultrafiltration of the blood and production of the pre-urine which then passes down the convoluted tubules for reabsorption.

So, the correct answer is option 'b'.
