The correct option is B <!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}-->
When winter, an old, old man
is all ready to depart,
<!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}-->
This line in the poem talks about how winter is coming to an end. Therefore, it can be best expressed as an old man whose life is almost at an end, instead of a young boy who is full of life. Here, winter is called an old man instead of being compared to an old man. So, this is a metaphor.
