The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion (A)**: The assertion states that "Anthrax is caused by a bacterium." This is true because anthrax is indeed caused by the bacterium *Bacillus anthracis*. 2. **Understanding the Reason (R)**: The reason states that "Anthrax develops only in buffaloes and can't be transferred to humans." This statement is incorrect. While buffaloes can be affected by anthrax, the disease can also affect a variety of other animals, including cattle, sheep, goats, and even wild animals. Furthermore, anthrax can be transmitted to humans, particularly through contact with infected animals or contaminated animal products. 3. **Evaluating the Truth of A and R**: - The assertion (A) is true. - The reason (R) is false. 4. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is incorrect. **Final Answer**: The correct option is that the assertion is true and the reason is false. ---
