Solution

The correct option is A equal to
In a series connection the net resistance is equal to the sum of all the resistances.
$R = R_{1} + R_{2} + R_{3} . . . . .$
Multiplying the LHS and RHS with current $I$ .
$I R = I_{1} R_{1} + I_{2} R_{2} + I_{3} R_{3} . . . . .$

Applying Ohm's law V = IR
$\Rightarrow V = V_{1} + V_{2} + V_{3} . . . . .$
