B
About 1.8 L/day
C
About 500 mL/day
D
About 18 L/day

Understand that glomerular filtration rate (GFR) refers to the volume of filtrate formed by the kidneys per unit time, typically measured in milliliters per minute (mL/min).
Recall that the average GFR for both kidneys combined in a healthy adult is approximately 125 mL/min.
Calculate the total volume of filtrate produced per day by multiplying the GFR by the number of minutes in a day: \(125 \, \text{mL/min} \times 60 \times 24\).
Convert the result from milliliters to liters by dividing by 1000, since 1000 mL equals 1 L.
Interpret the final value as the approximate daily volume of glomerular filtrate produced by both kidneys, which is about 180 liters per day.
