Final answer:
If a lion, the 'king of beasts,' runs in front of a train, it would realistically get hit due to the insufficient ability to influence the train's motion.
Step-by-step explanation:
When the king of beasts, typically referring to a lion, runs in front of a train, the realistic outcome is A) It gets hit. In the wild or in a setting where a train encounters an animal, natural instincts and physical abilities generally do not enable such an animal to stop the train, outpace it, or have any significant impact on the train's movement.
A collision with a train is unfortunately likely to result in serious harm or fatality for the animal. It's also important to note that the question might be a riddle or a joke, but as the answer is not provided in that context, the response is based on realistic outcomes.
