Missing settings in rigidbody 2d

Hello, this is my first unity project, I know absolutely nothing about programing and scripting, I’ve been following this tutorial Recorded Video Sessions on 2D in Unity 4.3 - Unity Learn but I have hit a roadblock, I can’t make some rigidbody 2d settings (body type, linear drag, etc…) appear no matter what I try, I have attached a picture with the missing setings, how do I make them show up? Thanks in advance.!

Can someone help me?
