Standard electrode potential of Zn and F...

Standard electrode potential of Zn and Fe are known to be (i) -0.76V and (ii) -0.44V 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
