A) \[E{{G}_{1}}=E{{G}_{2}}=E{{G}_{3}}\]
B) \[E{{G}_{1}}<E{{G}_{2}}<E{{G}_{3}}\]
C) \[E{{G}_{1}}>E{{G}_{2}}>E{{G}_{3}}\]
D) \[E{{G}_{1}}<E{{G}_{2}}>E{{G}_{3}}\]
Correct Answer: B
Solution :
In insulators, the forbidden energy gap is very large, in case of semiconductor it is moderate and in conductors the energy gap is zero.
