The correct answer is "Slow but steady wins the race" because the story illustrates the importance of perseverance and consistent effort. The Rabbit, who boasts about his speed, underestimates the Tortoise and takes a nap during the race. Meanwhile, the Tortoise continues to plod on steadily and ultimately wins the race. This teaches us that even though slow, consistent progress may seem less impressive, it can lead to success in the long run.
