Most widely used bioweapon is

Options

A. Bacillus subtilis
B. Pseudomonas putida
C. Bacillus anthracis
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding Bioweapons**:
- A bioweapon is defined as a biological agent that can cause harm or destruction to living beings. The term "bio" refers to living organisms, while "weapon" refers to something used to inflict damage.

2. **Identifying the Agent**:
- The question asks for the most widely used bioweapon. One of the most notorious biological agents is the bacterium **Bacillus anthracis**.

3. **Characteristics of Bacillus anthracis**:
- **Spore Formation**: Bacillus anthracis can form spores, which are resistant forms that can survive in harsh conditions. This ability allows it to spread easily in nature.
- **Diseases Caused**: This bacterium is known to cause severe diseases in both humans and livestock, primarily:
- Respiratory disorders
- Skin diseases

4. **Common Disease**:
- The most common disease caused by Bacillus anthracis is **anthrax**. This disease can be lethal and is a significant concern in both medical and bioterrorism contexts.

5. **Mode of Spread**:
- Due to its spore formation, Bacillus anthracis can be transmitted through air currents, making it particularly dangerous as a bioweapon since it can infect individuals over a wide area in a short period.

6. **Conclusion**:
- Based on the information gathered, Bacillus anthracis is recognized as the most widely used bioweapon due to its ability to cause severe diseases and its efficient mode of transmission.

### Final Answer:
The most widely used bioweapon is **Bacillus anthracis**.
