FYI, I dont reccomend putting your full name anywhere on the internet, and in the top right hand corner we can all see your name. Also to answer this Question I reccomend going to Shmoop.com and looking up "The Hunger Games Chapter 21 Summary" or just going on Google and searching "Chapter 21 summary of The Hunger Games" and it'll be the first link to pop up. Remember to put it in your own word and source it, DO NOT write it word for word, because that would be Plagiarism; and Plagiarism is illegal.
The correct answer in this question is option A. The sisters dislike Sunjata because he is male. A male offspring of the king can be an heir to his father's throne. There was also a prediction that the king's son will become a mighty ruler someday if the king marries an ugly woman who is Sunjata's mother.
