No way! I’m going to change it now-the correct answer is b. you should never have your profile open so anyone can see it. if it is youre allowing everyone in the world to access your profile and look at all you pictures and wall posts. as well as that you are letting people be able to copy your pictures and anyone could use them half way across the world and pretend to be you. when people have access to your profile and you dont know them they can see everything you have ever done on facebook and thats not good when you dont know a person.
