Solution

The correct option is A All are correct
We have,
1. unit of specific conductivity = $o h m^{- 1} c m^{- 1}$
2. specific conductivity of strong electrolytes decrease on dilution because the number of ions per unit area decreases
3. the amount of ion discharge during electrolysis is independent of resistance
4. electrochemical equivalent = $g / c o u l o m b$
Therefore, all the statements are correct
