Solution

The correct option is A increase
In a series connection the positive terminal of the first battery is connected to the negative terminal of the second battery.
And the Equivalent voltage of the battery is the sum of the voltage of individual cell.So, when two batteries are connected in series the voltage in the circuit will increases.
Therefore, A is correct option.
