Identify the correct statements regarding relationship between stress and immune system.

(A) The White Blood Cells within the immune system identify and destroy foreign bodies
(B) There are several kinds of red blood cells like T Cells, B Cells and natural killer cells
(C) T Cells increase immunological activity while T helper cells destroy invaders
(D) B Cells produce antibodies
(E) Immune functioning is better in individuals receiving social support

Choose the correct answer from the options given below:

(A), (D), (E) Only

The correct answer is Option (4) → (A), (D), (E) Only

(A) The white blood cells within the immune system identify and destroy foreign bodies – Correct. White blood cells (also called leukocytes) are the main players in the immune system. They recognize and attack pathogens such as bacteria and viruses, helping protect the body from infections.

(B) There are several kinds of red blood cells like T Cells, B Cells and natural killer cells – Incorrect.  T cells, B cells, and natural killer cells are types of white blood cells, not red blood cells. Red blood cells primarily carry oxygen and do not play a role in immunity.

(C) T Cells increase immunological activity while T helper cells destroy invaders – Incorrect. T helper cells assist other immune cells by releasing cytokines and activating them. It is the cytotoxic T cells (not T helper cells) that directly destroy infected or abnormal cells.

(D) B Cells produce antibodies – Correct. B cells are responsible for producing antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses.

(E) Immune functioning is better in individuals receiving social support – Correct. Psychological studies have shown that individuals with strong social support tend to have better immune functioning and are more resilient to stress and illness.
