The deficiency of vitamin K causes

Options

A. Haemorrhage
B. Lengthening time of blood clotting
C. Inflammation of tung
D. Both (1) & (2)

Answer

### Step-by-Step Solution:

1. **Understanding Vitamin K**: Vitamin K is a fat-soluble vitamin that plays a crucial role in the process of blood clotting. Its chemical name is phylloquinone.

2. **Identifying the Effects of Deficiency**: The deficiency of vitamin K leads to two main issues:
- **Hemorrhage**: This refers to excessive bleeding. When vitamin K levels are low, the body cannot effectively form blood clots, which are necessary to stop bleeding.
- **Lengthening of Blood Clotting Time**: This means that the time it takes for blood to clot is increased, making it harder for the body to stop bleeding when injuries occur.

3. **Interrelation of Symptoms**: The two symptoms (hemorrhage and lengthening of blood clotting time) are interrelated. If blood clotting takes longer, it naturally results in increased bleeding or hemorrhage.

4. **Conclusion**: Given the effects of vitamin K deficiency, the correct answer to the question is that it causes both hemorrhage and lengthening of blood clotting time. Therefore, the correct option is both option 1 and option 2.

5. **Sources of Vitamin K**: To prevent deficiency, it is important to include sources of vitamin K in the diet, such as green leafy vegetables.

### Final Answer:
The deficiency of vitamin K causes both hemorrhage and lengthening of blood clotting time.
