Nephron tubes filter waste products and transfer them into the collecting tubules.

C.

Gravity forces large particles to filter through capillary walls of the glomerulus.

D.

Bowman's capsules collect dissolved substances and transfer them to the peritubular capillaries.

Answer;

A. Pressure causes water and dissolved substances to filter through capillary walls of the glomerulus.

Explanation; During filtration the flow of blood in the glomerulus creates hydrostatic pressure in the glomerulus which forces molecules through the glomerular filtration membrane. Normal filtrate contains of water, glucose, amino acids, urea, creatinine, and solutes such as sodium chloride, calcium, potassium and bicarbonate ions.
