The correct answer is "baris ketiga dan empat". This is because the first and second lines talk about not keeping a broken needle in a box and not keeping a wrong word in one's heart. The third and fourth lines continue this pattern by saying that if there is a broken needle, it should not be kept in a box, and if there is a wrong word, it should not be kept in one's heart. Therefore, the correct answer is the third and fourth lines.
