If for Hydrogen \[{{\operatorname{C}}_{p}}- {{C}_{v}}\]= m and for Nitrogen \[{{\operatorname{C}}_{p}}- {{C}_{v}}\] = n where,\[{{\operatorname{C}}_{p}}\,and {{C}_{v}}\]refer to specific heat per unit mass respectively at constant pressure and constant volume, the relation between m and n is: [molar mass of Hydrogen = 2 and molar mass of\[{{\operatorname{N}}_{2}} = 28\]]

A) n = 14m          

B) n = 7m

C) m = 7n                        

D) m = 14n
