Solution
If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.
Explanation:
The assertion is correct because when sodium argentocyanide solution is treated with scrap zinc, silver is displaced and gets precipitated. The reason is also correct because zinc is more electropositive (more reactive) than silver, so it displaces silver from its complex. Hence, the reason correctly explains the assertion.
