The Correct Option is C

Solution and Explanation

The resistance \(R\) of a conductor is given by the formula \(R = \rho \frac{L}{A}\), where \(L\) is the length, \(A\) is the cross-sectional area, and \(\rho\) is the resistivity. If the length is doubled and the area is halved, the resistance increases by a factor of 4.
