Correct choice is (d) Zinc dissolution in dilute H2SO4 and rusting of iron

Explanation: Uniform corrosion is characterized by an electrochemical reaction that proceeds uniformly over the entire exposed surface. Zinc dissolution in dilute H2SO4 and rusting of iron are examples of uniform corrosion. Dezincification of brass in acids is an example of selective leaching.
