Solution

The correct option is D Exposing it to sunlight
Corrosion can be prevented by creating a barrier between the object and oxygen. Galvanisation is a process to prevent corrosion and so is painting. However, exposing to sunlight is not a method to prevent corrosion.
Thus, option D is correct.
