Answer:

Option (A) Resistance

Explanation:

In an electric circuit, the resistance acts as hindrance to the current flow. If a very high amount of resistance is added into an electrical circuit, then the current can be effectively reduced to zero.

Because, current is directly proportional to Voltage & inversely proportional to resistance in a circuit. (From Ohm's law i.e. V = IR)

If V is constant, and R is increased, then I will decrease.

A high resistance will lead to current eventually becoming zero.
