Correct option is (iv) None of the above
The product of resistivity and conductivity of a cylindrical conductor is constant
The product becomes
$\rho \times \sigma$, where pis resistivity and $\sigma$ is conductivity
We know that
$$
\rho=\frac{1}{\sigma}
$$
Hence there product is equal to 1 i.e., constant.
Hence it does no depend on any of the physical quantity
The product of resistivity and specific conductivity of a cylindrical conductor depends on
i) temperature
ii) material
iii) area of cross-section
iv) none of these
i) temperature
ii) material
iii) area of cross-section
iv) none of these
