Answer:
The correct answer is Pegasus frees himself from captivity, and he is rewarded by becoming a constellation in the night sky.
Step-by-step explanation:
In the poem "Pegasus in Pound", despite being a mythical and wonderful horse that had wings, Pegasus was held in captivity. They only took it out to offer it to a possible buyer.
When Pegasus can finally break free of that bondage, he heads for the stars. Let's look at the following quote:
"Then, with nostrils wide distended,
Breaking from his iron chain,
And unfolding far his pinions,
To those stars I have soared again"
Given this information we can say that the correct answer is Pegasus frees himself from captivity, and he is rewarded by becoming a constellation in the night sky.
