      Assertion (A) Semiconductors are solids with conductivities in the intermediate range from. Reason (R) Intermediate conductivity in semiconductor is due to partially filled valence band.  

    Answer:

                      (c) Assertion is correct statement but reason is incorrect statement. Semiconductors are solids with conductivities in the intermediate range varie from. Intermediate conductivity is due to small energy gap between valence band and conduction band. (A/so, refer to Q. 60)
