1.	Assertion: Galvanised iron does not rust. Reason: Zinc has a more negative electrode potential than iron.A. If both assertion and reason are true, and reason is the true explanation of the assertionB. if both assertion and reason are true, but reason is not the true explanation of the assertion.C. if assertion is true, but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - A R is the correct explanation of A (More negative electrode potential of zinc means higher oxidation potential. Hence, zinc is more easily oxidized than iron).
