According to Ohm's Law V = I*R
If voltage doubles, current doubles considering resistance to be constant.
If voltage doubles, current doubles considering resistance to be constant.

The question says 'a resistance', which means the resistance is not change.
When the Voltage is doubled in a resistance, from V=IR, then the only variable that will be changed is the current to double.
So, answer D.

From ohms law V = IR.
If 1 variables we have 2 more variables,
Until and unless any one variable is constant.
Answer cannot be predicted because data is insufficient.

According to V=IR, Here two right answer.
-> if current is constant resistance double. Then current unchanged (ANSWER B & C).
-> if resistance is constant current double.
I think. (ANSWER D).
-> if current is constant resistance double. Then current unchanged (ANSWER B & C).
-> if resistance is constant current double.
I think. (ANSWER D).

If voltage doubles then current is also doubled, taking resistance are to be constant i.e. from V =IR.
