A man painted his main gate made up of iron, to
(i) prevent it from rusting.
(ii) protect it from sun.
(iii) make it look beautiful.
(iv) make it dust free.
Which of the above statement(s) is/are correct?
Sunlight doesn’t harm iron. So there is no need to protect it from sun. Paint can’t avoid dust. So main reason behind painting the gate is to prevent it from rusting and to make it look beautiful.
