વાહક,અર્ધવાહક અને અવાહક માટે ફોરબિડન એનર્જી ગેપ (forbidden energy gap) માટેનો સાચો સંબંધ કયો છે?

• A
  $ \Delta E_{g, \text{conductor}} > \Delta E_{g, \text{semiconductor}} > \Delta E_{g, \text{insulator}} $
• B
  $ \Delta E_{g, \text{insulator}} > \Delta E_{g, \text{semiconductor}} > \Delta E_{g, \text{conductor}} $
• C
  $ \Delta E_{g, \text{conductor}} > \Delta E_{g, \text{insulator}} > \Delta E_{g, \text{semiconductor}} $
• D
  $ \Delta E_{g, \text{semiconductor}} > \Delta E_{g, \text{conductor}} > \Delta E_{g, \text{insulator}} $
