Solution

The correct option is A its kinetic energy increases but potential energy and total energy decrease
$K . E \propto \frac{1}{r}$
$P . E \propto - \frac{1}{r}$
$T . E \propto - \frac{1}{r}$
As electron shifts from excited state to ground state radius will decrease.
$\Rightarrow K . E ↑ P . E ↓ T . E ↓$
