B. `B_1`
C. `B_2`
D. `B_(12)`

Explanation

To determine which vitamin deficiency causes anemia, we can analyze the information provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding Anemia**:
- Anemia is a condition characterized by a lack of healthy red blood cells or hemoglobin in the blood, leading to reduced oxygen transport in the body.

2. **Identifying Vitamins**:
- The transcript mentions several vitamins: B1, B2, B6, and B12.

3. **Researching Vitamin Functions**:
- Vitamin B1 (Thiamine): Important for energy metabolism but not directly linked to anemia.
- Vitamin B2 (Riboflavin): Important for energy production and cellular function, but not primarily associated with anemia.
- Vitamin B6 (Pyridoxine): Involved in hemoglobin production but not the primary cause of anemia.
- Vitamin B12 (Cobalamin): Crucial for red blood cell formation and deficiency leads to a specific type of anemia known as pernicious anemia.

4. **Conclusion**:
- Based on the functions of these vitamins, Vitamin B12 is the most significant vitamin deficiency that causes anemia.

### Final Answer:
Anemia is primarily caused by the deficiency of **Vitamin B12**.
