\( X \) and \( Y \) are two metals. When burnt in air, \( X \) forms only oxide while \( Y \) forms oxide and nitride. The metals \( X \) and \( Y \) are :
(A) \( \mathrm{Ca} \) and \( \mathrm{Mg} \)
(B) \( \mathrm{Li} \) and \( \mathrm{Na} \)
(C) \( \mathrm{Na} \) and \( \mathrm{Mg} \)
(D) \( \mathrm{Na} \) and \( \mathrm{K} \)
