Both Statement $I$ and Statement $II$ are correct.

Vedclass · Answer

(A) Statement $I$ is correct because according to Bohr's postulate,the angular momentum of an electron in a stationary orbit is an integral multiple of $\frac{h}{2\pi}$,i.e.,$mvr = \frac{nh}{2\pi}$.Statement $II$ is correct because Bohr's model assumes electrons move in well-defined circular orbits with fixed velocity and position,which directly contradicts the Heisenberg uncertainty principle,which states that it is impossible to determine simultaneously the exact position and momentum of a subatomic particle.
