  Electrolytic conductor - Graphite
• B. Electronic conductor - Graphite
  Electrolytic conductor - Sulphuric acid
• C. Electronic conductor - Sulphuric acid
  Electrolytic conductor - Copper
• D. Electronic conductor - Sodium hydroxide
  Electrolytic conductor - Nitric acid

Answer 1

The correct option is B Electronic conductor - Graphite

Electrolytic conductor - Sulphuric acid
Electronic conductors are those which conduct electric current by the movement of electrons. Example: metals, graphite, etc.

Electrolytic conductors are those which conduct electric current by the movement of ions. These are called electrolytes. Example : salt solution, acids and alkalis.
