Answer:
Option A i.e nickle gets oxidized.
Explanation:
Actually in case of a chemical reaction, the more reactive element displaces the less reactive element from its salt solution.
In this case, nickel would be able to displace silver from its salt solution i.e. from the silver nitrate form. This reaction would be indicated by the color that appears.
Actually, silver nitrate is inorganic in nature. The formula for silver nitrate is AgNo3. It changes into black color whenever it is introduced into any organic compound.
The substance that reduces other substance from its salt solution actually acts as a reducing agent and itself gets oxidized. Here nickel displaces AgNo3 from its salt solution and hence gets oxidized or a reducing agent.
