Explanation
The correct answer is A: Euthanasia.
Mercy killing, also known as assisted suicide or voluntary euthanasia, refers to the act of intentionally ending the life of a person who is suffering from a terminal or incurable illness or condition, in order to relieve their suffering. This is done with the person's consent, or in some cases, at the request of the person's family members or legal representatives.
Euthanasia is a controversial and highly debated topic around the world, with opinions divided on whether it is a humane option for people suffering from incurable illnesses or whether it is morally wrong and should be illegal. There are different forms of euthanasia, including active euthanasia, where a person is given a lethal dose of medication, and passive euthanasia, where life-sustaining treatment is withdrawn or withheld.
Final Exit and Murphy's Death are terms that are not commonly used to refer to mercy killing or euthanasia. Final Exit is a book by Derek Humphry that advocates for the right to die and provides information on how to end one's life. Murphy's Death is not a commonly used term and does not have any specific meaning in the context of euthanasia or mercy killing.
Santhara is a religious practice in Jainism, also known as Sallekhana, where a person voluntarily fasts to death when they feel that their life has served its purpose, and they wish to achieve a higher level of spirituality. Santhara is not related to euthanasia or mercy killing, as it is a voluntary act of self-denial rather than an act of ending someone's life to relieve their suffering.
