The Passage B supports the theme that perseverance pays off.
Explanation:
The tortoise with a pretty daughter is a story of how a king declared that any daughter born in the kingdom more beautiful than the prince's wives , should be killed along with her family members.
There was a tortoise to whom, a beautiful daughter was born. While the mother wanted the girl to be killed to save themselves, the tortoise was against it and saved his daughter by keeping her hidden.
When the prince accidentally saw her,he fell in love with her and wanted to marry her. The king wanted to kill the beautiful damsel but, when he saw her beauty, he had a change of heart.
This shows that the Tortoise was wisest of all Men and animals, as his perseverance paid off. He without getting scared chose to protect his daughter and waited for the king to realize, how wrong he was to pass this law.
In return for his perseverance , he not only got his daughter married to the king's son , but also got half of the Kingdom along with riches and slaves.
