Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Zinc is used in galvanizing because zinc can be made to stick to iron and does not rust. In addition, when you cut it, the zinc will cover the iron at the point where it is cut. The whole process makes sheet iron last much longer.
