• A. Wedges
• B. Screw
• C. Frames
• D. Self-Locking Screw

Answer: (A)

The idea being tested is how a wedge works as a simple machine. A wedge is a triangular block formed by two inclined planes joined at a thick edge. When you drive the thick end between two objects, the wedge pushes the objects apart or locks them together by the forces exerted on the inclined faces. That triangular shape and the way it converts a driving push into separation or holding between parts is exactly what this description fits. The other devices described—screws that translate rotation into linear motion, frames as rigid supports, and self‑locking screws—operate by different mechanisms and aren’t defined by a triangular block placed between items to hold or move them.
