Which is the correct relation for forbidden energy gap in conductor, semi conductor and insulator [RPMT 2001; AIEEE 2002]

A)            \[\Delta E{{g}_{\text{c}}}>\Delta E{{g}_{\text{sc}}}>\Delta E{{g}_{\text{insulator}}}\]

B)            \[\Delta E{{g}_{\text{insulator}}}>\Delta E{{g}_{\text{sc}}}>\Delta E{{g}_{\text{conductor}}}\]

C)            \[\Delta E{{g}_{\text{conductor}}}>\Delta E{{g}_{\text{insulator}}}>\Delta E{{g}_{\text{sc}}}\]

D)            \[\Delta E{{g}_{\text{sc}}}>\Delta E{{g}_{\text{conductor}}}>\Delta E{{g}_{\text{insulator}}}\]
