The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.
I’d say A is probably the correct answer , but if not A , then definitely B.

Number 3, "has more people than ever before" is correct. As there are more people, there is a greater need more resources.
