The tempenature coefficient of rasistance (\alpha) is positive for conductors and negative for semiconductors " where, \propto=\frac{\Delta R}{R \Delta T}
Therefore, with the increase in temperature the electrical resistance increases for conductors but decreases for semicorductors
The correct option is (2)
