$Statement-1$ is True,$Statement-2$ is False

(C) $Statement-1$ is True because Germanium is a semiconductor with a small band gap (approx $0.7 \ eV$).$Statement-2$ is False. In a solid,atomic energy levels overlap to form energy bands due to the interaction of a large number of atoms,which results in a significant energy spread,not an infinitesimally small one.

Medium

$STATEMENT-1$: Band gap in germanium is small.
$STATEMENT-2$: The energy spread of each germanium atomic energy level is infinitesimally small.
