The relationship between current, voltage, and resistance in a circuit is best described by Ohm's Law, which states that voltage is equal to the current multiplied by the resistance (V = I × R). According to this principle, if the current is held constant, a decrease in resistance will indeed lead to an increase in voltage. Thus, when considering the scenario where voltage increases as resistance decreases while keeping the current the same, it aligns perfectly with the concept outlined by Ohm's Law.

This view highlights how voltage and resistance interact within a circuit under specific conditions. In practical terms, if you have a fixed current demanding a certain level of energy to flow through the circuit, a lesser resistance will require a higher voltage to maintain that current, confirming that the relationship expressed in the correct option is valid and supported by the fundamentals of electrical circuits.
