Answer 1

The correct choice is (c) 5-6 L

To explain: In an average adult about 5-6 L of blood is present. Blood consists of corpuscles suspended in a fluid called plasma in the proportion of 45 parts of corpuscles (cells) to 55 parts of plasma. The percentage of cells in the blood is called the haematocrit value or packed cell volume (PCV).
