ANS:A - more

The diameter of a washer as compared to the nut is typically more. Washers are used to provide a larger bearing surface under the head of a bolt or nut, which helps distribute the load applied by the fastener over a larger area. This helps prevent damage to the surface being clamped and can also help prevent the fastener from loosening over time due to vibration. Washers are generally specified by their hole diameters, and they are usually larger in diameter than the nut they accompany. This ensures that the washer extends beyond the edges of the nut, providing the desired bearing area. Therefore, the correct answer is that the diameter of the washer is typically more than the diameter of the nut.
