Solution
The correct option is A90.1Ohm−1cm2 At infinite dilution the equivalent conductance of strong electrolytes furnishing same number of ions is same.
For this case, Both NaF and KF are strong electrolyte and also furnish 2 ions in the solution.
Hence, Both will have same equivalent conductance.
