Solution
The correct option is B 
Monocytes are the largest of all types of leucocytes and somewhat amoeboid in shape. They are motile and phagocytic in nature and engulf bacteria and cellular debris. Their lifespan is about 10-20 hours. Neutrophils are quite large and have many lobed nucleus and abundant granules. Neutrophils are phagocytic in nature and the most numerous of all.B-lymphocytes form about 20% of white blood cells. They produce antibodies and are thus involved in immune response.Basophils have a nucleus which is three lobed and have less number of coarse granules. Their granules take basic stain and they secrete heparin, histamine and serotonin
