Solution

The correct option is A S1 is wrong and S2 is correct
Solution:- (B) S1 is wrong and S2 is correct

On dilution, number of ions per ml decreases so conductivity decreases hence S1 is wrong.

$Λ_{M} = \frac{1000 \times k}{C}$

On dilution C and k both decrease but the effect of C is more dominating so $Λ_{M}$ increases hence S2 is right.
