The following compounds have been arranged in order of their increasing thermal stabilities. Identify the correct order: \( \mathrm{K}_{2} \mathrm{CO}_{3} \) (I), \( \mathrm{MgCO}_{3} \) (II), \( \mathrm{CaCO}_{3} \) (III), \( \mathrm{BeCO}_{3} \) (IV)
(A) \( \mathrm{I}\mathrm{II} \) III \( \) IV
(B) IV \( \) II \( \) III \( \) I
(C) \( \mathrm{IV}\mathrm{II}\mathrm{I} \) III
(D) \( \mathrm{II}\mathrm{I} V\mathrm{II}\mathrm{I} \)
