A) 20%
B) 50 ng/min
C) 1500 ng/min
D) 7500 ng/min
E) 10%

The filtered load of a solute is calculated by multiplying the glomerular filtration rate (GFR) by the plasma concentration of the solute. Here, GFR is 150 mL/min and the plasma concentration of solute X is 10 ng/mL. Therefore, the filtered load is 150 mL/min * 10 ng/mL = 1500 ng/min.
