The correct Answer is:
To solve the assertion-reason question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that a 0.2% solution of phenol is an antiseptic while a 1% solution is a disinfectant. - **Evaluation**: This is correct. Antiseptics are typically used in lower concentrations to inhibit microbial growth on living tissues, while disinfectants are used in higher concentrations to kill microorganisms on inanimate objects. 2. **Understanding the Reason**: - The reason states that antiseptics are also called disinfectants. - **Evaluation**: This statement is incorrect. While both antiseptics and disinfectants serve to kill or inhibit the growth of microorganisms, they are used in different contexts. Antiseptics are safe for use on living tissues, while disinfectants are not. 3. **Conclusion**: - Since the assertion is true and the reason is false, the correct answer to the assertion-reason question is that the assertion is true but the reason is false. ### Final Answer: - **Assertion**: True - **Reason**: False - Therefore, the correct option is: Assertion is true, but reason is false.
