Assertion `(A) :` Galvanized iron does not rust.
Reason `(R): Zn` has a more negative electrode potential than `Fe`.

Options

A. If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`.
B. If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R)` is incorrect.
D. If `(A)` is incorrect, `(R)` is correct.

Answer

a

Explanation

Both `(A)` and `(R)` are correct and `(R)` is the correct explanation of `(A)`.
More `-ve` electrode potential of `Zn` means less reduction potential or high oxidation potential. Hence, `Zn` is more easily oxidized than `Fe`.
