Solution

The correct option is D Both Statement and Explanation are correct but Explanation is not the correct explanation for Statement.
Bohr proposed that angular momentum of electron in an orbit is quantized. According to deBroglie, $: m v r = n \frac{h}{2 π}$
The same relationship is obtained from the fourth postulate of Bohr's model of atom. Thus the angular momentum mur is an integral multiple of $\frac{h}{2 π}$ .

Thus, both Statement and Explanation are correct but Explanation is not the correct explanation for Statement.
