For a dilute solution of a strong electrolyte, which of the following facts is correct?

For a dilute solution of a strong electrolyte, the graph between ${\mathrm{A}}_{\mathrm{m}}$ and $\sqrt{c}$ is linear

The ions are farther apart with a drop in concentration or a rise in dilution, and as a result, interionic attractions are reduced. This is due to the full dissociation of a strong electrolyte in the solution, which causes the number of ions to remain constant. Since ions move more slowly at higher concentrations due to stronger inter-ionic interactions, conductance decreases as concentrations rise. As dilution continues indefinitely, the conductance rises until it reaches a maximum limiting value.

Hence option C is correct
