The correct Answer is:

To solve the question regarding the assertion and reason provided, we will analyze both statements step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "Galvanized iron is protected from rusting." - Galvanized iron is iron that has been coated with a layer of zinc. This coating serves as a protective barrier against moisture and oxygen, which are the main contributors to rusting (the formation of hydrated ferric oxide). 2. **Understanding the Reason (R)**: - The reason states that "Zn is less reactive than Fe." - To evaluate this statement, we need to consider the reactivity series of metals. In the reactivity series, zinc (Zn) is actually more reactive than iron (Fe). This means that zinc can displace iron from its compounds and react more readily with oxygen. 3. **Evaluating the Relationship Between (A) and (R)**: - Since galvanized iron is indeed protected from rusting due to the presence of zinc, the assertion (A) is correct. - However, the reason (R) is incorrect because it incorrectly states the reactivity of zinc compared to iron. Zinc is more reactive than iron, not less. 4. **Conclusion**: - Based on the analysis, we find that: - Assertion (A) is correct. - Reason (R) is incorrect. - Therefore, the correct option is (c): If (A) is correct, but (R) is incorrect.
