Among the following choose the correct relation between molarity and normality

A) $\text{Normality}=n\times \text{molarity}$   $\to$  n indicates,

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