26. In a jurisdiction that follows the common law for homicide offenses, which crimes should the court instruct the jury on?

B is the correct answer. Voluntary manslaughter is a killing that would otherwise be murder but is distinguished by the existence of adequate provocation. Provocation is adequate if it would arise a sudden and intense passion for the ordinary person, the defendant has in fact been provoked, there was not a sufficient cooling off period between the provocation and the killing, and the defendant did not cool off. In this case, the killing was intentional. However, the issue is if there was adequate provocation to reduce the crime from murder to voluntary manslaughter. Thus, the jury should be instructed on both of these crimes.

A is incorrect. In this case, the defendant intentionally killed the neighbor. The only issue is if there was adequate provocation. Therefore, involuntary manslaughter is not a proper crime to instruct the jury on in this case.

C is incorrect. As stated above, it is proper to instruct the jury on voluntary manslaughter and murder to determine whether there was adequate provocation. Involuntary manslaughter doesn't apply because the killing was intentional.

D is incorrect. This answer is only partially correct. Although instructing the jury on voluntary manslaughter is proper, the primary issue is whether there was adequate provocation to reduce the crime from murder to voluntary manslaughter, not involuntary manslaughter. Because involuntary manslaughter is inapplicable here, the jury should only be instructed on murder and voluntary manslaughter.
