Answer»

Correct answer is (d) WINDERS

Best explanation: Winders are steps that are narrower on ONE side than the other. They are used to CHANGE the direction of the stairs without landings. A series of winders form a CIRCULAR or spiral STAIRWAY. When three steps are used to turn a 90° corner, the middle step is called a kite winder as a kite-shaped quadrilateral.
