    A) All \[{{E}_{c}},{{E}_{g}},{{E}_{v}}\] increase

    B) \[{{E}_{c}}\]and\[rms\]increase, but\[{{E}_{g}}\]decreases

    C) \[{{E}_{c}}\]and \[{{E}_{v}}\]decrease, but\[{{E}_{g}}\]increases

    D) All \[{{E}_{c}},\,{{E}_{g}},\,{{E}_{v}}\] decrease

    Correct Answer: C

    Solution :

    If lattice constant of semiconductor is decreased, then\[{{E}_{c}}\]and\[{{E}_{y}}\]decrease but\[{{E}_{g}}\] increases.
