Options

A. They are low-cost weapons.
B. They cause more casualties than conventional weapons.
C. They are extremely difficult to detect
D. Bacterium E.coli created letter scare in 2001.

Answer

**Step-by-Step Solution:**

1. **Understanding Bioweapons:**
Bioweapons, also known as germ warfare, involve the use of biological toxins or infectious agents to harm or kill humans. They are considered a form of warfare and can have devastating effects.

2. **Analyzing the Statements:**
We need to evaluate each of the provided statements to determine which one is incorrect.

3. **Statement 1: "They are low-cost weapons."**
- This statement is incorrect. Bioweapons are not low-cost; they require extensive research, development, and resources, making them expensive to produce.

4. **Statement 2: "They cause more casualties than conventional weapons."**
- This statement is correct. Bioweapons can potentially cause more casualties than traditional weapons like guns and bombs due to their ability to spread and affect large populations.

5. **Statement 3: "They are extremely difficult to detect."**
- This statement is also correct. Bioweapons can be hard to detect because symptoms may take time to appear, allowing the agent to spread before it is identified.

6. **Statement 4: "Bacterium E. coli created let us scour in 2001."**
- This statement is incorrect. The anthrax attacks in 2001 were caused by Bacillus anthracis, not E. coli. Therefore, this statement is misleading.

7. **Conclusion:**
The incorrect statements are:
- Statement 1: They are low-cost weapons.
- Statement 4: Bacterium E. coli created let us scour in 2001.

Since the question asks for an incorrect statement, both Statement 1 and Statement 4 can be considered incorrect, but the primary focus should be on Statement 1 as it is a general misconception about bioweapons.

**Final Answer:**
The incorrect statement with respect to bioweapons is: "They are low-cost weapons."
