ACurrent remains the same
BCurrent fluctuates randomly
CCurrent decreases
DCurrent increases

✓ Correct answer: C. Current decreases Ohm's Law (I = V/R) dictates that current is inversely proportional to resistance when voltage is constant. If resistance increases, the current will decrease proportionally.
