The equivalent conductances at infinite dilution of HCl and NaCl are 426.15 and 126.15 mho `cm^(2) g eq^(-1)` respectively. It can be said that the mobility of :
A. `H^(+)` ions is much more than that of `Cl^(-)` ions
B. `Cl^(-)` ions is much more than that of `H^(+)` ions
C. `H^(+)` ions is much more than that of `Na^(+)` ions
D. `Na^(+)` ions is much more than that of `H^(+)` ions
