With increase in temp, resistance increases in metal so electric conductivity decreases.
While in case of semi-conductor, with an increase in temp, electrical conductivity increases.
While in case of semi-conductor, with an increase in temp, electrical conductivity increases.

In metals the conductivity is due to movement of free electrons. So When temperature increases, the vibration of metal ions increases. This results in increase in resistance of metal and hence, decrease in conductivity.
So, the option B is correct.
So, the option B is correct.
