'Renunciation' is the act of formally rejecting or giving up something, such as a claim, right, or possession. It can refer to voluntarily relinquishing a position, title, belief, or way of life. 'Rejection' is the correct answer as it captures the core meaning of saying no to something or refusing to accept it. The other options (Destiny, Destruction, Confidence) don't reflect the meaning of voluntarily giving something up.
