The filtration pressure at the glomerulus is equal to

A) glomerular hydrostatic pressure - (capsular hydrostatic pressure + interstitial fluid osmotic pressure).
B) capsular hydrostatic pressure + capsular colloid osmotic pressure + glomerular hydrostatic pressure.
C) glomerular hydrostatic pressure - (capsular hydrostatic pressure + blood colloid osmotic pressure).
D) (capsular hydrostatic pressure + capsular colloid osmotic pressure) - glomerular hydrostatic pressure.
E) glomerular hydrostatic pressure - (capsular hydrostatic pressure + capsular colloid osmotic pressure).
