Decreasing concentration of the electrolyte

(B) According to Ostwald's dilution law,the degree of dissociation $(\alpha)$ of a weak electrolyte is related to the concentration $(C)$ by the expression $\alpha = \sqrt{\frac{K_a}{C}}$.Thus,the degree of dissociation is inversely proportional to the square root of the concentration of the electrolyte.Therefore,decreasing the concentration of the electrolyte increases the degree of dissociation.
