Innate immunity is provided by

Options

A. Antibody
B. Neutrophils
C. B-cells
D. T-cells

Answer

**Step-by-Step Solution:**

1. **Understanding Innate Immunity**: Innate immunity is the body's first line of defense against invading microorganisms. It is a non-specific form of defense that responds quickly to pathogens.

2. **Identifying the Options**: The options given are:
- Antibodies
- Neutrophils
- B cells
- T cells

3. **Analyzing Each Option**:
- **Antibodies**: These are proteins produced by B cells in response to specific antigens. They are part of the adaptive immune response, not innate immunity.
- **Neutrophils**: These are a type of white blood cell (leukocyte) and are the most abundant in humans. They play a crucial role in the innate immune response by attacking and destroying invading pathogens.
- **B cells**: These are part of the adaptive immune system and are responsible for producing antibodies.
- **T cells**: These are also part of the adaptive immune system, involved in cell-mediated immunity.

4. **Conclusion**: Since neutrophils are essential for the innate immune response and are the most abundant leukocytes in the body, they provide innate immunity.

5. **Final Answer**: The correct answer is **neutrophils**.
