The correct answer is C. Homicide.
Homicide is the killing of one human being by another. It can be classified as murder, manslaughter, or justifiable homicide. Murder is the unlawful killing of a human being with malice aforethought. Manslaughter is the unlawful killing of a human being without malice aforethought. Justifiable homicide is the killing of a human being in self-defense or in the defense of another.
Fratricide is the killing of one’s brother or sister. Regicide is the killing of a king or queen. Genocide is the deliberate killing of a large group of people, especially those of a particular ethnic group or nation.
In some jurisdictions, a man can be sentenced to death for killing another human being. The death penalty is a controversial issue, and there is no consensus on whether it is a just punishment for homicide.
