Q.117) Innate immunity is the first line of defense and is present at the time of birth.

It is non-specific, meaning it does not target specific pathogens but defends against a wide range of invaders.

This includes physical barriers (like skin), physiological barriers (like stomach acid), cellular defenses (like phagocytes), and inflammatory responses.

(1) Humoral Immunity – Part of acquired immunity; involves B-cells producing antibodies.

(2) Acquired Immunity – Develops after birth upon exposure to specific pathogens.

(4) Cell-mediated Immunity – Also acquired; involves T-cells attacking infected or abnormal cells.
Hence, the correct answer is option (3): Innate Immunity.
