Answer

The correct answer is (D). The resistance depends on resistivity, length, and cross-sectional area.

Work Step by Step

At a given temperature, we can write an expression for the resistance of a wire: $R = \frac{\rho~L}{A}$ Thus resistance depends on resistivity, length, and cross-sectional area. The correct answer is (D).
