Question

according to the provided information, which of the following is an essential element to arrest a subject for murder?
killing with sudden provocation
accidental killing without intent
unlawful killing of a human being or fetus with malice aforethought
unlawful killing in self-defense

Explanation:

Murder is defined as the unlawful killing of a human being (or fetus in some jurisdictions) with malice aforethought—this includes intent to kill, intent to cause grievous harm, reckless indifference to human life, or intent to commit a dangerous felony. The other options are not murder: sudden provocation typically reduces a killing to manslaughter, accidental killing without intent is not a criminal homicide (or is manslaughter), and self-defense makes a killing lawful, not murder.

Answer:

Unlawful killing of a human being or fetus with malice aforethought
