An appropriate summary for the article "A Most Troublesome Element" is the last option - C. Arsenic is a naturally occurring, poisonous element that has threatened the health of humans since the Middle Ages.
It clearly states what the whole article is about.
If it's about the most happiest Surprise you ever had then I suggest you should do it your self because it's about you. what if your teacher asked that what happened next? it won't be nice to lie. i would love to help but sometimes you just never had a happy Surprise. I'm not trying to be rude but you should really do this one yourself and also because it's about you not me. I'm really sorry .
What are the option choice?
