Identify the false statements
I. Antigen binding site of an antibody is found between two light peptide chains.
II. The pathogen of elephantiasis is transmitted ot a healthy person through the bite of same mosquito species which also cause malarial disease.
III. Lymphoid tissues are also located within the lining of the major tracts called mucosal-associated lymphoid tissue.
IV. Increase intake of coffee or tea can cause indigestion, insomnia and disturb renal functions.
V.Anaphylactic shock is an autoimmune reaction which involves all the tissues of the body that results in drastic fall in blood pressure.

Options

A. I,III,V
B. II,IV,V
C. I,II,V
D. All of above

Answer

To identify the false statements among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement I: Antigen binding site of an antibody is found between two light peptide chains.**
- This statement is **false**. The antigen binding site of an antibody is formed by the variable regions of one heavy chain and one light chain, not between two light chains.

2. **Statement II: The pathogen of elephantiasis is transmitted to a healthy person through the bite of the same mosquito species which also cause malarial disease.**
- This statement is **false**. Elephantiasis is caused by filarial worms, which are transmitted by mosquitoes of the genus Culex, while malaria is transmitted by Anopheles mosquitoes. Therefore, they are not transmitted by the same mosquito species.

3. **Statement III: Lymphoid tissues are also located within the lining of the major tracts called mucosal-associated lymphoid tissue.**
- This statement is **true**. Mucosal-associated lymphoid tissue (MALT) is indeed found in the lining of major tracts such as the gastrointestinal tract, respiratory tract, and urogenital tract.

4. **Statement IV: Increase intake of coffee or tea can cause indigestion, insomnia and disturb renal functions.**
- This statement is **true**. Excessive consumption of coffee or tea can lead to indigestion, insomnia, and may affect renal functions due to the caffeine content.

5. **Statement V: Anaphylactic shock is an autoimmune reaction which involves all the tissues of the body that results in drastic fall in blood pressure.**
- This statement is **false**. Anaphylactic shock is not an autoimmune reaction; it is an allergic reaction that can cause a severe drop in blood pressure and affects multiple body systems.

### Conclusion:
The false statements are:
- **I**: Antigen binding site of an antibody is found between two light peptide chains.
- **II**: The pathogen of elephantiasis is transmitted to a healthy person through the bite of the same mosquito species which also cause malarial disease.
- **V**: Anaphylactic shock is an autoimmune reaction which involves all the tissues of the body that results in drastic fall in blood pressure.

### Final Answer:
The false statements are **I, II, and V**.
