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 |
