Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Orbital angular momentum of an electron $\sqrt{l (l + 1)} \frac{h}{2 π}$ .
Angular momentum of an electron in an orbit $\frac{n h}{2 π}$ .
Spin angular momentum of an electron $\sqrt{s (s + 1)} \frac{h}{2 π}$ .
So angular momentum of d-orbitals is $\sqrt{6} \frac{h}{2 π}$ .
