Options

A. Sodium carbonate
B. Sodium oxalate
C. Sodmm chloride
D. Sodium hydroxide

Answer

To answer the question "Which one of the following anticoagulant is added in blood during storage?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Anticoagulants**:
- Anticoagulants are substances that prevent or delay the coagulation (clotting) of blood. They are often referred to as blood thinners.

2. **Purpose of Anticoagulants**:
- The main purpose of adding anticoagulants to blood during storage is to increase the shelf life of the blood by preventing it from clotting.

3. **Identifying Common Anticoagulants**:
- There are several anticoagulants used in medical practices, such as heparin, sodium citrate, EDTA, and sodium oxalate.

4. **Specific Anticoagulant for Blood Storage**:
- Among these, sodium oxalate is commonly used as an anticoagulant during blood storage.

5. **Mechanism of Action**:
- Sodium oxalate works by binding to calcium ions in the blood. Calcium is essential for the clotting process; thus, when sodium oxalate binds with calcium, it forms a precipitate that depletes the calcium ions from the blood, preventing clot formation.

6. **Conclusion**:
- Therefore, the anticoagulant that is added to blood during storage is sodium oxalate.

### Final Answer:
The anticoagulant added in blood during storage is **sodium oxalate**.
