Answer: D) Instead of giving in to death, people should fight against it.
Explanation: In the given excerpt we can see that the speaker is encouraging people to don't giving in to death ("Do not go gentle into that good night"), instead the speaker claims that people should fight really hard against death ("Old age should burn and rave at close of day; Rage, rage against the dying of the light"), so the statement that best describes the main idea of the excerpt is the corresponding to option D.
