# The product of resistivity and conductivity of a conductor with uniform cross-section depends on

$\begin {array} {1 1} (A)\;Temperature & \quad (B)\;Material \\ (C)\; Area \: of \: cross-section & \quad (D)\;None\: of\: these \end {array}$

The product of resistivity and conductivity is identically equal to unity
Ans : (D)
