What is the noun form for the action of forcing material out through a small opening to shape it?

• A. Mechanism
• B. Cross-section
• C. Extrusion
• D. Correlation

Answer: (C)

The main concept here is naming a manufacturing process where material is pushed through a small opening to form a shape. The correct noun is extrusion. Extrusion describes the act or process of forcing material through a die to create long, continuous profiles—common in plastics and metals for tubing, channels, or rails. The term comes from extrude, meaning to push out. The other options don’t fit because mechanism refers to the device or method used, cross-section is a cut view of the inside, and correlation means a relationship between things.
