Answer:

Of the given options, option B is most apt.

Explanation:

Any mechanical instrument used to multiply force may be called a Simple Machine. It changes the magnitude and direction of an applied force. Simple machines increase the output force through a proportional decrease in movement of the load. They form the fundamental basis for all complicated modern machinery.

The basic simple machines are wheel and axle, pulley, lever, inclined plane, wedge, and screw.
