Without having the paragraph, I can only help you to find the answer. As you read the paragraph, you need to find the main idea. What is the paragraph mostly about? Thinking about that, what are the possible outcomes from this main idea? For example, if you have a story about a tornado hitting a small town, you could say that one of the outcomes would be everyone coming together to help one another put the town back together.
Answer: Hm well personally I think none of the above. I think you should take a scientific question and research it (ie. What happens if you burn soap bars) but I guess if I had to choose one from here then A?
