Answer: Eosinophils
Explanation:
Eosinophils can be defined as a type of white blood cell whose number increases in the blood when there is any infection in the body or at the time of any allergic reaction or even in case of cancer.
Presence of more than 500 eosinophils per mL of blood is normal in an adult but more than 1500 eosinophils per mL of blood shows infection and if lasts for several months then the condition will be hypereosinophils.
So, the correct answer is eosinophiles.
