Question

a. levers
b. inclined planes
c. wedges
d. screws

Explanation:

A wedge is a simple machine that can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. Axes, scissor - blades, and nail points are used to split or cut materials by applying force, which is the function of a wedge. Levers have a fulcrum and are used for lifting or moving objects by applying force at a distance from the fulcrum. Inclined planes are flat surfaces at an angle used for moving objects up or down with less force. Screws are used for fastening or lifting by converting rotational motion into linear motion.

Answer:

C. wedges
