Which outcome results from Fermi level location inside a semiconductor's band?

💡 Explanation

Intrinsic semiconductivity emerges because thermal excitation bridges the band gap, populating the conduction band due to the Fermi level residing within the band gap. Therefore, option A is correct, rather than high external sensitivity or insulation which require different energetic configurations.
