# Q. 14.3     Carbon, silicon and germanium have four valence electrons each. These are characterised by valence and conduction bands separated by energy bandgap respectively equal to $\inline (E_{g})_{C},(E_{g})_{Si}$  and $\inline (E_{g})_{Ge}$. Which of the following statements is true?                (a) $\inline (E_{g})_{Si} < (E_{g})_{Ge}< (E_{g})_{C}$                (b) $\inline (E_{g})_{C} < (E_{g})_{Ge}> (E_{g})_{Si}$                (c) $\inline (E_{g})_{C} > (E_{g})_{Si}> (E_{g})_{Ge}$                (d) $\inline (E_{g})_{C} = (E_{g})_{Si}= (E_{g})_{Ge}$

$\inline (E_{g})_{C} > (E_{g})_{Si}> (E_{g})_{Ge}$
