Answer:
D)
Step-by-step explanation:
I honestly don't like this question. It's a really poor question. But anyway, here's the explanation:
1) All search results are somewhat relevant. They have the keyword "cell phone" in every result. So none should be considered off-topic.
2) Matching personal opinion with given answer choices.
My personal list if any, would have been 3, 1, 2, 4.
But since the author has helped as out, 3 and 2 are guaranteed to be the top choices, the last part is determining whether search result 4 is more relevant compared to 2.
Since I believe 1 is somewhat relevant, A and C are negated. Leaving, B and D. In this situation, I would prefer 1 than 4 since search result 4 doesn't exactly help your research paper compared to search result 1. Therefore, the only choice is D.
