Identify type of blood corpuscles A and B in the given diagram and select the correct option indicating names with their respective characteristics
1. Erythrocyte-500-1100 per mm3 helps in transport of gases Megakaryocyte-produced in liver, form fragments called platelets 
2. Thrombocyte-Stains with basic stain non-phagocytic, formed from macrophages Basophil-helps in coagulation of blood
3. Neutrophils- Polymorphonuclear cell, phagocytic in nature Lymphocytes- Agranuclocyte, constitutes 25%to 35% of total WBCs 
4. Eosinophil- Constitutes about 1 to 3% of total number of WBCs its number increases in allergic conditions Monocytes- actively motile differentiates into macrophages and destroys bacteria by phagocytes
