If we connect cells in parallel, the current capacity will get added. If we not cells in series, the voltage of each cell will be added to find total battery pack voltage.
In the above question, the five cells are connected in parallel.
The total current capacity will be 20 *5 = 100Ah.
The total voltage of battery pack will be 3 volts.
The energy of the battery pack will be 3 volts * 100 Ah = 300 Wh.

The correct answer is option 03.
