Quizplus · Accepted Answer

According to the activity series, zinc (Zn) is above iron (Fe) and therefore has a higher tendency to undergo oxidation, making it a more reactive metal than iron. As a result, if both iron and zinc are present in a solution and are connected electrically, zinc will preferentially undergo oxidation, serving as a sacrificial electrode for iron. Therefore, option A is the best choice as a sacrificial electrode for iron.
