• A. Copper
• B. Sodium
• C. Calcium
• D. Magnesium \bigskip

Hint:

A more reactive metal displaces a less reactive metal from its salt solution.

The Correct Option is A

Iron is more reactive than copper but less reactive than sodium, calcium, and magnesium. Therefore, iron can displace copper from its salt solution based on the reactivity series.
