Answer:
The line is a metaphor for:
B. A life without dreams.
Explanation:
Let's take a look at the poem:
Hold fast to dreams
For if dreams die
Life is a broken-winged bird
That cannot fly.
Hold fast to dreams
For when dreams go
Life is a barren field
Frozen with snow.
As we can see above, in the first stanza the author compares life to a broken-winged bird after mentioning the death of dreams. What the author means is that a life without dreams is as purposeless as a bird that cannot fly. Dreams are what makes life worth living, what gives us a sense of purpose. Without them, there is no reason to go on.
