Solution

The correct option is B 30 mmHg
Colloid osmotic pressure, also called as oncotic pressure is a form of osmotic pressure exerted by proteins, notably albumin.
The total oncotic pressure of an average capillary is about 28 mm Hg with albumin contributing approximately 22 mm Hg of this oncotic pressure.Therefore, the correct answer is option B.
