Hint We will discuss the properties of screws. Then we will choose an appropriate option out of the four. We are asked here about the type of material a screw is. More precisely it is asked what type of modified instrument is a screw. Thus, we will discuss the properties of screws. Then we will choose an appropriate option out of the four.

Complete Step By Step Solution
An inclined plane is just a simple plane at an angle with the horizontal. The small angle change in the horizontal direction changes the properties to a great extent.
Now,
A screw can be dismantled into two parts.
First is the bulge of the screw. Then is the thread of the screw.
Again,
If we similarly dismantle the thread of the screw, we observe that it is simply an inclined plane wrapped around a cylinder.

Hence, the correct option is (C).

Note: A screw is a modified inclined plane. It is an inclined plane wrapped around a cylinder. A screw is a modified inclined plane. More precisely speaking, it is an inclined plane wrapped around a cylinder.
