Correct Answer: Option B
Explanation

When metals are heated in air, they react with oxygen to form specific oxides. Sodium oxide is not the primary product when sodium metal is heated in air; instead, sodium burns with an intense orange flame to primarily form sodium peroxide. Na\(_2\)O is typically only formed when there is a limited supply of oxygen.
