Answer:
B). An extended metaphor
Explanation:
The given excerpt has been taken from William Shakespeare's 'Blow, Blow, Thou Winter Wind.' The poem explores the idea of life and foolishness. The speaker says that a fake friend is more harmful and causes more ache than the winter's harsh wind. He compares the wind to the character of such a friend to emphasize this idea. Thus, it would be considered as an extended metaphor as the comparison continues throughout the poem(the wind's bite is less fatal than the ingratitude of such a man,' like the wind's bite is not seen, similarly his friend has betrayed and frogot all the past favors). Thus, option B is the correct answer.
