Options

A. Vitamin `B_(1)`
B. Vitamin `B_(2)`
C. Vitamin `B_(6)`
D. Vitamin `B_(12)`

Explanation

To determine which B group vitamin can be stored in our body, we need to analyze the properties of the B vitamins listed in the question.

### Step-by-Step Solution:

1. **Identify the B Vitamins**: The question provides four options:
- Vitamin B1 (Thiamine)
- Vitamin B2 (Riboflavin)
- Vitamin B6 (Pyridoxine)
- Vitamin B12 (Cobalamin)

2. **Understand Solubility**: Vitamins can be classified based on their solubility:
- **Water-soluble vitamins**: These vitamins dissolve in water and are not stored in significant amounts in the body. They need to be consumed regularly.
- **Fat-soluble vitamins**: These vitamins can be stored in the body's fatty tissues and liver.

3. **Classify the B Vitamins**:
- **Vitamin B1 (Thiamine)**: Water-soluble
- **Vitamin B2 (Riboflavin)**: Water-soluble
- **Vitamin B6 (Pyridoxine)**: Water-soluble
- **Vitamin B12 (Cobalamin)**: Although it is water-soluble, it is unique among the B vitamins because it can be stored in the liver for a longer duration compared to the others.

4. **Conclusion**: Based on the classification, Vitamin B12 is the only B group vitamin that can be stored in the body for an extended period. The other options (B1, B2, and B6) are water-soluble and cannot be stored.

### Final Answer:
The B group vitamin that can be stored in our body is **Vitamin B12**.
