Explanation:
Betty Parris is the first to fall ill, and the reason Hale is summoned to Salem. After being discovered by her father, as she danced with the other girls in the woods, Betty becomes sick and unresponsive. Source(s) The Crucible
There are several types of conflicts in literature:
You have:
1. Man versus Self
2. Man versus another character
3. Man versus nature (ex. To build a Fire by Jack London)
4. Man versus Society (ex: Atlas Shrugged)
In this case I would think that the conflict is found in D: Perseus's effort to escape from the Gorgons after he kills Medusa.
The reason why I feel that D is the best option is because There is a cause and effect of the conflict. Pereus caused a death and now that brings conflict into the picture especially since it says he has to put effort into escaping the other characters (Gorgons).
Good luck and I hope this helped.
