Answer

To determine which of the following options is not used as a bioweapon, we will analyze each option provided:

1. **Bacillus anthracis**: This bacterium is known to cause anthrax, a serious infectious disease. It has been used as a bioweapon in the past, particularly in bioterrorism incidents. Therefore, it is used as a bioweapon.

2. **Botulinum toxin**: This is a potent neurotoxin produced by the bacterium Clostridium botulinum. It can cause severe illness and has been considered for use as a bioweapon due to its lethality. Thus, it is also used as a bioweapon.

3. **Bacillus thuringiensis toxin**: This is a bacterium that produces toxins used primarily in agriculture as a pesticide against insects. It is not known to be used as a bioweapon against humans or animals. Therefore, this option is not used as a bioweapon.

4. **Smallpox**: The smallpox virus is a highly contagious and deadly virus that has been used as a bioweapon in the past. It is known for its potential to cause widespread outbreaks. Hence, it is used as a bioweapon.

Based on this analysis, the answer to the question is:

**C. Bacillus thuringiensis toxin** is not used as a bioweapon.
