Solution

The correct option is A
True

Less reactive metals such as aluminum, zinc, and iron react with steam to liberate dihydrogen gas.
$M e t a l + s t e a m \to M e t a l o x i d e + H y d r o g e n$

Examples: When magnesium reacts with steam, it produces magnesium oxide and hydrogen gas

$M g (s) + 2 H_{2} O (g) ⟶ M g (O H)_{2} (s) + H_{2} (g)$

When Aluminum reacts with steam, it produces Aluminum oxide and hydrogen gas

$2 A l (s) + 3 H_{2} O (g) ⟶ A l_{2} O_{3} (s) + 3 H_{2} (g)$

When Iron reacts with steam, it produces Iron Oxide and hydrogen gas

$3 F e (s) + 4 H_{2} O (g) ⟶ F e_{3} O_{4} (s) + 4 H_{2} (g)$
