A machine, a simple machine, to be specific is a device that changes either the magnitude or direction of force. It uses mechanical advantage to multiply force. Simple machines transform energy into work. 

The answer would then be letter A.

There are six simple machines, which are pulley, lever, inclined plane, wheel and axle, screw and wedge. The answer is inclined plane as listed above. the other choices are complex machines that are simple machines combined. 

The answer would then be B.

A screw is a simple machine which is a modified version of an inclined plane. It is an inclined plane that circles around a central point. Another one would be the wedge. The wedge is an inclined plane that is moved using something else like an axe. 

The answer is then A.
