The Correct Option is B
Solution and Explanation
A stair step consists of a tread (the horizontal surface on which the foot is placed) and a riser (the vertical face between two consecutive treads).
A winder is a tapered, wedge-shaped tread used where a stair turns; nosing is the projecting edge of the tread; going is the horizontal distance from one riser to the next.
Hence the vertical portion between treads is the riser.
Answer: (2) Riser
A winder is a tapered, wedge-shaped tread used where a stair turns; nosing is the projecting edge of the tread; going is the horizontal distance from one riser to the next.
Hence the vertical portion between treads is the riser.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
