Solution

The correct option is C Greasing
Polishing and washing are common methods used to restore shine in a number of objects. Sandpaper is used to scrape away the rust from metals to expose the shiny surface again.
Greasing is a common lubricant which is used to reduce friction in metals. Its application also prevents metals from rusting. However, it cannot restore shine in them.
