Its not A because aor resistance is the force of an object passing through air. 

 

Its not B because kenetic is the energy in motion. 

 

Its not C because fluid force is the force of water on an object.

 

Its D because static friction is when one object is on top of another or resting. Which can be two seperate surfaces. And they can be divided into two categories. 

 

Hope this helps ;P
