Resistance is the property of the material, not the circuit characteristics so that the answer is wrong. The correct answer is voltage will be doubled since V is proportional to I.

In a series combination, current is constant. As per current voltage drop varies. Resistance is constant. If current is doubled, voltage has to double.

R = V/I.
If I is doubled, then the equation becomes,
R = V/2(I) thus, 1/2 is the equivalent of the resistance.
I Hope this helps.

Resistance never changes with a change in current. So the answer is wrong.

How is that possible? i=v/r, when i doubles , v is doubled na? and isn't the resistance of a circuit always constant ?

V=IR,
when series current doubles ,
I=2I,So,
V=2I(R),
when series current doubles voltage doubles,
And,
R=V/2I,
when series current doubles resistance half, As per equation,
Please clear anybody with the answer.

Because in series I is always same so we consider voltage is also same, if we change in current first consider change in resistance.
