Answer
Magnesium
Reason — Magnesium metal burns in presence of carbon dioxide to give magnesium oxide and carbon (black).
Iron does not burn in carbon dioxide because it is not reactive enough to take oxygen from CO2. Aluminium does not burn in carbon dioxide because it is covered by a protective oxide layer (Al2O3). Copper is even less reactive as it cannot take oxygen from CO2 at all.
