Answer:
D. All of the above
Explanation:
All of them are correct because...
A.) Standing up straight and walking confidently gives people the "Im not weak" sort of vibe. It lets people know that you "mean buisness" and you're not afraid of them.
B.) Making eye contact with someone bothering you and <em>firmly </em>saying "leave me alone" lets the person know that you're being serious, and NOT joking around. Usually, they'll leave you alone.
C.) Never open the door for someone you don't know, especially if you're home alone. Instead, ignore whoevers at the door, or open it when you're with a trusted adult.
Since all 3 of these tips protect yourself from becoming a victim of violence, the correct answer is 'D.) All of the above'
I hope this helps! :)
