Solution

The correct option is C Blood minus blood corpuscles and plasma proteins
In humans, Nephron is main filtration unit. It has afferent arteriole which brings blood, which has to pass through an endothelial cell of capillary and basement membrane cells ( podocytes ) of Bowman's capsule. These 2 barriers have the different diameter, thus allowing only substance having diameter that of or less than of barriers such as urea, uric acid, amino acid, glucose, creatinine potassium, sodium, and vitamins. Blood consists of corpuscles and plasma proteins which do not match the diameter of membranes, thus are not present in the filtrate.
hence answer is option C.
