5.43 eV

Explanation:

from the energy level diagram, we can calculate the energy difference between c level and the ground state. the difference is 4.86 eV which is less than the 5.43 eV of choice 4. therefore, a photon of that energy cannot be emitted

Electric potential differnce is defined as:
$\Delta V=\int_{a}^{b}E\cdot dl$
If we asume the electric field is constant we get:
$\Delta V=\int_{a}^{b}E\cdot dl=E\Delta L$
We need to calculate the electic field strenght:
$F=qE\\

$
$E= F/q\\
E=\frac{25\cdot 10^{-6}}{50 \cdot 10^{-6}}=0.5 \frac{V}{m}$
We can now calculate the potential difference:
$\Delta V=E\Delta L=0.5 \frac{V}{m}\cdot15m=7.5V$
