Answer: option <span>B.The total mass of A and C, which are carbon and oxygen, is equal to the mass of B, which is carbon dioxide.

Explanation:
1) The combustion of carbon is represented by the chemical equation:
C + O₂ → CO₂
2) The law of conservation of mass states that the mass of the products is equal to the mass of the reactants.
3) The reactants are C and O₂, while the product is CO₂.
4) The masses given are: A: 12 g, B: 44 g, and C: 32 g
Then, 12g + 32 g = 44 g, this is A + C = B.
Then, B represents the product, which is CO₂, whose molar mass is 44 g/mol.
Since, the molar mass of C is 12 g/mol, it is A; and since the molar mass of O₂ is 32, it is C.
Therefore, the answer is the option B.
