As we learnt in 

Molar Conductivity with Concentration -

- wherein

molar conductivity increases with decrease in concentration.

 

The process given in the question does not work on weak electrolytes and NH_{4}OH is weak electrolyte ,the rest are strong.

\therefore Solution is 2


Option 1)

KCl
