Answer:
The best answer is indeed the first option: <u>Wake up and quit wasting time inside. Get outside and into the light!</u>
Explanation:
In his poem "Song of the Open Road", Whitman talks of not wanting to be confined any longer. The speaker has decided to live out in the open, to travel and see the world. He even claims that healthy and beautiful people are formed by air and light, by spending their time outdoors. The speaker feels free and welcomed by the world, which is now his home.
In the excerpt we are studying here, the speaker is inviting someone, possibly the reader, to come with him. He's urging the reader to leave the confinement of his own house and embracing freedom outside. Thus, the best paraphrase for the passage is "Wake up and quit wasting time inside. Get outside and into the light!"
