Final answer:
In 'Beauty and the Beast,' the enchantress offers the prince a magical rose for shelter, which becomes central to the curse and the plot of the story.
Step-by-step explanation:
In the film Beauty and the Beast, the enchantress offers the selfish young prince a rose in exchange for a night's shelter. This rose is not just an ordinary rose, but a magical one that is closely linked to the curse placed upon the prince and his castle. The rose serves as a countdown to the prince's fate; if he does not learn to love and earn someone else's love in return before the last petal falls, he is doomed to remain a beast forever.
