The answer is C. Magnesium.

A sacrificial anode is a metal that is more reactive than the metal it is protecting. 1 It corrodes instead of the other metal. 2 Magnesium is more reactive than iron, so it can be used as a sacrificial anode to protect iron from corrosion.

Copper, lead, and silver are all less reactive than iron, so they would not be effective as sacrificial anodes. Follow for more.
