Among the following choose the correct relation between molarity and normality

                                                     i) Basicity of acids

                                                     ii) Acidity of bases

                                                    iii) Total change present on  anions                           

                                                    (or)  cations per formula unit.

                                                     iv) Change in orientation number of

                                                           oxidizing agent or reducing agent.

B)  $\frac{\text{Normality}}{\text{Molarity}}=\text{Basicity}\text{of}\text{an}\text{acid}$

C) $\frac{\text{Normality}}{\text{Molarity}}=\text{Acidity}\text{of}\text{a base}$      

D) $\text{Molarity of an acid}=\frac{\text{Normality}}{\text{its basicity}}$
