Verified Answer :

An infection in the body might result in a sudden increase in the activity of white blood cells.

Answer:

The correct answer would be (3) increase in the activity of white blood cells.

White blood cells (WBCs) or leucocytes are the primary cells of the immune system which protect our body against pathogens as well as other foreign particles.

There are five types of white blood cells present in our body; eosinophils, neutrophils, basophils, monocytes, and lymphocytes.

Neutrophils and monocytes are phagocytic in nature. Lymphocytes (B cells, T cells, and natural killer cells) are mainly associated with antigen-antibody reactions. Basophils release histamines which help in inflammatory responses.

Thus, an infection in the body might result in a sudden increase in the activity of white blood cells.
