• A. L/hour
• B. L/min
• C. %/day
• D. mL/hour

Hint:

Clearance is a key concept in understanding how the body processes drugs, often used to calculate dosages in medical settings.

Answer 1

The Correct Option is A

Clearance, often used in pharmacokinetics and physiology, measures the rate at which a substance (like a drug or waste) is removed from the body, typically by organs like the kidneys or liver. It is defined as the volume of plasma cleared of a substance per unit of time. The standard unit for clearance is liters per hour (L/hour), as it reflects the volume of fluid (in liters) cleared over a period of time (in hours).
Thus, the correct answer is L/hour.
