Solution

The correct option is C $25 V$
In the circuit diagram, the cells are connected in series.
In a series connection of cells, the total potential difference will be the sum of potential differences of the individual cells.
$∴$ Effective potential difference $= V_{1} + V_{2} + V_{3} + V_{4} + V_{5}$
$= 5 + 7 + 8 + 4.2 + 0.8 = 25 V$ .
