Question

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

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

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