NEET (UG) 2025 — Question 158
Which of the following type of immunity is present at the time of birth and is a non-specific type of defence in the human body ?
- Option A:
Acquired Immunity
- Option B:Correct
Innate Immunity
- Option C:
Cell-mediated Immunity
- Option D:
Humoral Immunity
Answer: B
Step-by-step solution
Innate immunity is present from birth and provides non-specific defense against pathogens. It includes physical barriers, phagocytes, and inflammatory responses that do not require prior exposure. Acquired immunity is specific and develops after exposure, so it is not present at birth. Cell-mediated and humoral immunity are components of acquired immunity, not innate immunity. Therefore, the correct answer is B.
