Final answer:
If a person convicted of causing serious bodily injury when trying to evade a peace officer, the maximum imprisonment is 5 years.
Step-by-step explanation:
In the given scenario, a person convicted of causing serious bodily injury when trying to evade a peace officer can face a maximum imprisonment of 5 years (option b). However, they leave out an important detail - if both prisoners remain silent, due to insufficient evidence, they would receive the least amount of jail time. The dilemma arises because if both prisoners betray each other, they face a moderate jail sentence, and if only one prisoner betrays and the other remains silent, the betrayer would get a release while the silent prisoner receives a long sentence.
If they both defect (betray each other), they will receive a five-year sentence. If both remain silent, they will get only a two-year jail term due to weak evidence. The optimal outcome for the prisoners collectively is to cooperate with each other and remain silent, leading to the lightest penalty under the circumstances.
