Standard electrode potentials of \[Zn\] and \[Fe\] are known to be (i) \[-0.76\,V\] and (ii) \[-0.44\,V\] respectively. How does it explain that galvanization prevents rusting of iron while zinc slowly dissolves away

A)                 Since (i) is less than (ii), zinc becomes the cathode and iron the anode

B)                 Since (i) is less than (ii), zinc becomes the anode and iron the cathode

C)                 Since (i) is more than (ii), zinc becomes the anode and iron the cathode

D)                 Since (i) is more than (ii), zinc becomes the cathode and iron the anode
