Answer 1

Answer:

Correct option is

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Coating of iron with zinc to prevent corrosion is called galvanization.

Steel is dipped in a bath of molten zinc. The zinc coated iron is called galvanized iron. Zinc (E

o

=−0.763V) is stringer reducing agent than iron (E

o

=−0.44V) and is more easily oxidized than iron . Thus during corrosion, Zn is oxidized instead of Fe.
