What is the order in which conduction takes place in the materials ?(starting from the materials that is highly conductive to that of the least )

  1. Puremetals-->Nonmetals-->Alloys-->liquids-->gases

  2. Puremetals-->Alloys-->Nonmetals-->liquids-->gases

  3. Nonmetals-->Alloys-->Puremetals-->liquids-->gases

  4. All materials exhibit same conductivity

B Correct answer
Explanation

Electrical conductivity follows the order: pure metals (highest) > alloys > nonmetals > liquids > gases (lowest). Pure metals like copper and silver have the highest conductivity due to free electron movement. Alloys have reduced conductivity, nonmetals are semiconductors/insulators, and gases are the poorest conductors.
