JEE Main 2023 Physics question on Current Electricity

As shown in the figure, a network of resistors is connected to a battery of 24V with an internal resistance of 3Ω. The currents through the resistors $R_4$ and $R_5$ are $I_4$ and $I_5$ respectively. The values of $I_4$ and $I_5$ are:

1. A.
   $I_4 = \frac{8}{5}$ A and $I_5 = \frac{2}{5}$ A
2. B.
   $I_4 = \frac{6}{5}$ A and $I_5 = \frac{24}{5}$ A
3. C.
   $I_4 = \frac{2}{5}$ A and $I_5 = \frac{8}{5}$ A
4. D.
   $I_4 = \frac{24}{5}$ A and $I_5 = \frac{6}{5}$ A
