D. Jonas raises an army to violently overthrow the industry leaders.
Explanation:
A contrived ending to the story is one created in a way that seems artificial and unrealistic. The most contrived ending would be the one where Jonas raises an army to violently overthrow the industry leaders.
The rest of the options seem more or less possible. Jonas' supporters could turn their back on him, the industry leaders' plan could backfire, or they could ruin Jonas' reputation. These endings would seem believable. However, it would be impossible for Jonas to raise an army. An individual wouldn't be able to do that in real life, which is why this type of ending wouldn't make sense.
