Answer:
The crime would be C. Involuntary manslaughter.
Step-by-step explanation:
Manslaughter is different from murder because it does not have the intent to kill. Generally, vehicular accidents fall into this category because mostly the drivers are reckless and this results in a fatality. However, they do not have the intent to kill.
Involuntary manslaughter means the kill was unintentional and was the product of recklessness which can be clearly understood in this example.
In the example we can see that the motorist runs the stop sign, which is a reckless action, and kills the pedestrian, the result of the reckless action.
The other options (A, B and D) are not the correct choice because the motorist's intent was not to kill so it was not first degree murder nor was the intent to do serious bodily injury.
