C Correct answer
Explanation

Semiconductors have an energy band gap (also called bandgap) typically around 1 electron volt (eV) at room temperature. Conductors have no energy gap, while insulators have large gaps exceeding 6 eV, which prevents electron conduction. This intermediate gap size makes semiconductors useful for electronic devices.
