Solution

The correct option is A
${A l}_{2} O_{3}$

Aluminium reacts with oxygen present in the air to form aluminium oxide. The reaction involved is:

$4 A l (s)$ + $3 O_{2} (g)$ $\to$ $2 {A l}_{2} O_{3} (s)$

Aluminium oxide is a protective layer formed on the aluminium body which prevents further oxidation of aluminium.
