The energy gap in case of which of the following is less than $ 3 eV $?

In insulators,which of the following statements is correct regarding their energy bands?

The energy gap in semiconductors is of the order of ........ $eV$.

This question has Statement $1$ and Statement $2$. Of the four choices given after the Statements,choose the one that best describes the two Statements.
Statement $1$ : $A$ pure semiconductor has a negative temperature coefficient of resistance.
Statement $2$ : On raising the temperature,more charge carriers are released into the conduction band.

In a good conductor,the energy gap between the conduction band and the valence band is:

The state of the energy gained by valence electrons when the temperature is raised or when an electric field is applied is called as:
