Carbon silicon and germanium have four valence electrons each these are characterised by valence and conduction bands separated by energy band gap respectively equal to which of the following statement is true
(a) `(E_(g))_(Si)lt(E_(g))_(Ge)lt(E_(g))_(c )`
(b)`(E_(g))_(c )lt(E_(g))_(Gelt(E_(g))_(Si)`
(c )`(E_(g))_(c )gt(E_(g))_(Si)gt(E_(g))_(Ge)`
`(d)(E_(g))_(c )=(E_(g))_(si)=(E_(g))_(Ge)`

Explanation

the energy band gap of carbon is maximum as it is an isulator follwed by silicon semiconductor and then germanium also semiconductor The correct option is
