Vedclass · Answer

(A) In a semiconductor,at room temperature,thermal energy is sufficient to break some covalent bonds,which generates electron-hole pairs. Therefore,free electrons are present at room temperature. At $0 \ K$,a semiconductor behaves as a perfect insulator because there is no thermal energy to break bonds,meaning there are no free electrons. Thus,option $A$ is incorrect.
