I would say the correct answer is A. <span>Despite the snowy and windy weather, a flock of young birds still manages to eat and survive. The imagery in the poem is dark and depressing. Bare trees, snow, dark wind are all the signs of forthcoming death, which is imminent. But even though the landscape is described as cruel and unforgiving, the flock of birds is still cheeping, eating and piping. Their song is certainly not pleasant to the ears, their flying is not vivacious, but it exists - which is the most they can hope for.</span>
The central idea is the same as the main idea. Most of the time, the main idea is mentioned in the Title. Without reading the essay, I do not know what the central/main idea is.
Choice A is my top choice in this question.
The answer is b hope this helps:)
Since the sentence is correct W.R.T faulty reference.
So option D is the right answer
