Question

Statement 1: For $n=3,l$ may be $0,1$ and $2$ and ${}^{\prime }{m}^{\prime }$ may be $0,\pm 1and\pm 2.$
Statement 2: For each value of $n$, there are $0$ to $(n-1)$ possible values of $l$; for each value of $l$, there are $0$ to $\pm$ values of $m$.

• 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 $1$.
