Answer:

Option A

Step-by-step explanation:

Ohm's law state that at constant temperature, the current flowing through the conductor is directly proportional to the potential difference applied across the conductor.

V = IR

Where, V is the potential difference, I is the electric current and R be the resistance of the conductor.

As resistance increases, current should be decreases to keep the potential difference constant.

In the question, as potential difference is same, so current is decreases.

Well, you can pretty much see it with this formula :

I = V/R

If the resistance (R) is increased, the amount of I will be increased.

so the answer would be : A. The current decreases

hope this helps
