ANSWER

In any graph of molar conductivity vs

C

,

a weak electrolyte gives a curved decreasing graph

strong electrolytes give straight-line decreasing graphs, in which the graph of stronger electrolyte will always be above the graph of the comparatively weaker electrolyte.

In option [B], Graph III is curved and corresponds to NH

4

OH which is a weak electrolyte. Graph II & I respectively represent NaCl and HCl. (∵HCl is a stronger electrolyte among the two).
