The energy gaps \[({{E}_{g}})\] between valence band and conduction band for diamond, silicon and germanium are in the order:

A)  \[{{E}_{g}}\](diamond) >\[{{E}_{g}}\](silicon)>\[{{E}_{g}}\](germanium)

B)     \[{{E}_{g}}\](diamond) <\[{{E}_{g}}\](silicon)<\[{{E}_{g}}\](germanium)

C)     \[{{E}_{g}}\] (diamond)=\[{{E}_{g}}\](silicon)=\[{{E}_{g}}\](germanium)

D)     \[{{E}_{g}}\](diamond) >\[{{E}_{g}}\](germanium)>\[{{E}_{g}}\](silicon)
