# As the temperature of a metallic conductor is increased, the product of resistivity and conductivity

$\begin {array} {1 1} (A)\;Increases & \quad (B)\;Decreases \\ (C)\; Remains\: constant & \quad (D)\;May \: increase\: or\: decrease \end {array}$

$Resistivity = \frac{1}{conductivity}$
Product of resistivity and conductivity is equal to a constant.
Ans (C)
