Detailed Solution

Ohm's law asserts that, provided certain physical parameters, such as the wire's length or temperature, remain constant, the current flowing through a conductor between two places is directly proportional to the voltage across the two points. Option A is inaccurate as a result.
The amount of current passing through a wire is inversely correlated with its resistance, meaning that the higher the resistance, the lower the current. Option B is therefore erroneous.
The current flowing through a wire is directly proportional to the potential difference applied across its end, according to Ohm's law, as can be seen from the diagram above. Option D is wrong, while option C is correct as a result.
