Vedclass · Answer

(C) The property of increasing conductivity with an increase in temperature is a characteristic feature of semiconductors.Semiconductors are typically formed by covalent bonding (e.g.,Silicon,Germanium).Metals (metallic bonding) show a decrease in conductivity with an increase in temperature.Ionic solids are generally transparent to visible light and are insulators.Therefore,the solid described is formed by covalent bonding.
