The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided: ### Step 1: Evaluate the Assertion The assertion states that "Hydrometallurgy is used for the extraction of Ag and Au." - **Explanation**: Hydrometallurgy is a method that utilizes aqueous chemistry to extract metals from their ores. It is particularly effective for less reactive and electropositive metals, such as silver (Ag) and gold (Au). Therefore, this assertion is **true**. ### Step 2: Evaluate the Reason The reason states that "Hydrometallurgy is different from pyrometallurgy." - **Explanation**: Hydrometallurgy and pyrometallurgy are indeed different processes. Hydrometallurgy involves the use of aqueous solutions to extract metals, while pyrometallurgy involves the extraction of metals through heating and melting processes at high temperatures. Thus, this reason is also **true**. ### Step 3: Determine the Relationship Between Assertion and Reason Now we need to determine if the reason correctly explains the assertion. - **Analysis**: While both statements are true, the reason does not explain why hydrometallurgy is used for the extraction of silver and gold. It simply states that hydrometallurgy is different from pyrometallurgy without linking it to the assertion about the extraction of these metals. ### Step 4: Conclusion Based on the evaluations: - Both the assertion and the reason are true. - However, the reason does not provide a correct explanation for the assertion. Thus, the correct answer is **Option B**: Both assertion and reason are true, but the reason is not the correct explanation of the assertion. ---
