Choose the correct statement regarding the resistance of a wire.
A. While maintaining a constant voltage V, the current I increases when the resistivity rho of a wire increases.
B. The resistivity rho is inversely proportional to the resistance R of a wire.
C. The resistance is inversely proportional to the length of the wire L.
D. The resistivity does not depend on the temperature of most metal wires.
E. While unmaintaining a constant voltage V, the current I increases when the resistivity rho of a wire decreases.
