Question

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?

1. A. Acquired Immunity
2. B. Innate Immunity (Correct answer)
3. C. Cell-mediated Immunity
4. D. Humoral Immunity

Correct Answer

Option B — Innate Immunity

Detailed Solution & Explanation

The correct answer is Innate Immunity.

Key Points

• Innate immunity is a non-specific defence present from birth, providing various barriers to the entry of foreign agents.
• Acquired immunity is pathogen-specific and develops with memory; humoral (B-cell) and cell-mediated (T-cell) responses are types of acquired immunity.
