Magnesium
Zinc
Gold
Copper

उत्तर
Gold
Explanation:
According to the metal reactivity series, a displacement reaction can only occur if a more reactive metal attempts to replace a less reactive metal in a solution. Magnesium, zinc, and copper are all located above silver in the series, meaning they are more reactive and can easily displace it. Gold, however, sits below silver in the reactivity series, making it less reactive and completely incapable of displacing silver from the AgNO3 solution.
