a. levers
b. inclined planes

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 things apart by applying force, which is the function of a wedge. Levers have a fulcrum and are used to lift or move objects with less force. Inclined planes are sloping surfaces used to move objects up or down with less force. Screws are used to hold things together or to lift objects by converting rotational motion into linear motion.

Answer:

C. wedges
