Which of the following is an example of "involuntary manslaughter"?

Involuntary manslaughter typically occurs when a person causes the death of another unintentionally, often as a result of reckless or negligent behavior. Driving under the influence and causing a fatal accident is a clear example of this because it demonstrates a disregard for the safety of others. The act of driving while impaired indicates negligence, and if it leads to someone's death, it fits the criteria for involuntary manslaughter.

The other options do not align with the definition of involuntary manslaughter. Killing someone in a premeditated plan reflects intent and is more aligned with murder. Using lethal force in self-defense indicates a justified act of self-protection, which is not a criminal act under the law. Accidentally bruising a person in a fight involves minor injury and does not rise to the level of causing death, which is a key aspect of manslaughter.
