The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Kappa Particles**: Kappa particles are genetic elements found in certain strains of bacteria, particularly in the context of bacteriophages. They can influence the behavior of the host organism. 2. **Identifying the Question**: The question asks for the minimum number of kappa particles required for an individual to become a "killer" strain. 3. **Analyzing the Options**: The options provided are 660, 400, and 150. We need to determine which of these numbers is the minimum required for the killer phenotype. 4. **Referencing Known Information**: According to the information provided in the video transcript, it is stated that at least a minimum of 400 kappa particles is necessary for the killer strain to express its lethal characteristics. 5. **Selecting the Correct Answer**: Since 400 is the minimum number of kappa particles required for the killer phenotype, the correct answer is option C, which is 400. 6. **Conclusion**: Therefore, the answer to the question is that kappa particles make an animal killer when their number in an individual is **400**. ---
