C

7 kΩ7\text{ k}\Omega

D

12 kΩ12\text{ k}\Omega

Correct Answer

Option A

Detailed Explanation

Option A is correct because it accurately represents the principle of conservation of mass, which states that in a closed system, the mass of reactants must equal the mass of products. This is demonstrated in the chemical reaction shown, where the total number of atoms of each element remains constant before and after the reaction, ensuring that the equation is balanced. Other options may misrepresent the stoichiometry or fail to account for the conservation laws, leading to incorrect interpretations of the chemical process. Understanding this principle is crucial for analyzing chemical reactions and predicting the outcomes based on reactant quantities.
