The correct option is option D ("His children").
Oedipus decides to stab his eyes as a self-inflicted punishment due to the excruciating shame and remorse he feels after killing his father and marrying his mother. In addition, he also felt that his actions were what brought the prophecies of the plague to life, causing him even more pain and regret. After Oedipus blinds himself with a golden brooch, his greatest concern is definitely shown for his children above everything else.
Hope this helps!
