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

$C$ and $Si$ both have the same lattice structure,having $4$ bonding electrons in each. However,$C$ is an insulator whereas $Si$ is an intrinsic semiconductor. This is because:

Carbon, silicon, and germanium atoms have four valence electrons each. Their valence and conduction bands are separated by energy band gaps represented by $(E_g)_C$, $(E_g)_{Si}$, and $(E_g)_{Ge}$ respectively. Which one of the following relationships is true in their case?

Choose the $FALSE$ statement from the following.

Write the electronic configuration of $Si$ and $Ge$.

The resistivity of a semiconductor at room temperature is in between
