Question

Statement 1: The diffusion rate of oxygen is smaller than that of nitrogen under identical conditions
Statement 2: Molecular mass of nitrogen is smaller than that of oxygen

• A. If both Statement $1$ and Statement $2$ are true and the Statement $2$ is the correct explanation of the Statement $1$ .
• B. If both Statement $1$ and Statement $2$ are true but Statement $2$ is not the correct explanation of the Statement $1$ .
