the valence band is partially empty and the conduction band partially filled.

(D) In semiconductors at room temperature,the thermal energy is sufficient for some electrons to overcome the forbidden energy gap. As a result,some electrons jump from the valence band to the conduction band. Consequently,the valence band becomes partially empty and the conduction band becomes partially filled.
