Answer 1

Right option is (a) haematocrit value

The best I can explain: The percentage of cells in the blood is called the haematocrit value or packed cell volume (PCV). The majority of the corpuscles in the blood are red blood cells (erythrocytes), others being white blood cells (leucocytes) and platelets (thrombocytes).
