- gaseous conductors
- semiconductors
- metallic conductors
- light emitting diodes

The Correct Option is C
Solution and Explanation
Ohm's law states that the current passing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. This law is applicable to materials that have a linear relationship between current and voltage, such as metallic conductors, where the resistance remains constant with respect to changes in voltage. For gaseous conductors, semiconductors, and light emitting diodes (LEDs), the relationship between current and voltage is non-linear, so Ohm's law does not apply in the same manner.
The correct option is (C): metallic conductors
