Solution

The correct option is A Magnesium
Magnesium has almost no reaction with cold water. It reacts slowly with hot water to give the slightly soluble magnesium hydroxide and hydrogen.
Magnesium burns in steam to produce white magnesium oxide and hydrogen gas. Very clean magnesium ribbon has a very slight reaction with cold water. After several minutes, some bubbles of hydrogen form on its surface, and the coil of magnesium ribbon usually floats to the surface.
Hence, option A is correct answer.
