Solution

The correct options are
A Germanium
C Silicon
D Gases
Ohm's law cannot be applied to semiconductors like germanium, silicon etc. Also gaseous conductors do not obey ohm's law. The reason behind this is that the resistance of these substances changes with temperature drastically.
For metals, eventhough resistance changes with temperature, current remains proportional to voltage. Hence, metals obey ohm's law.
