Ohm`s Law states that the..

A
current in a circuit is directly proportional to voltage.
B
power in the circuit is inversely proportional to the square of the current.
C
current in a circuit is directly proportional to the resistance of the circuit.
D
current in a circuit is inversely proportional to voltage.

Refer to figure.

Ohm’s law states that the current passing through a conductor between two points is proportional to the voltage across the two points.

If remembering the definition is not how your memory works, I recommend remembering the equation:

U = I x R

Therefore we can say that the voltage is proportional to the circuit’s current.
