Answer:
The line is a metaphor for:
B. A life without dreams.

</em>
<em>That cannot fly.

<u>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.</u>
