Explanation:
When a drop of water is placed on a steel plate or the lid of a tiffin, it will move faster compared to the other substances mentioned in the options. This is due to the property of surface tension.

Surface Tension:
Surface tension is the force that acts on the surface of a liquid, causing it to behave like a stretched elastic sheet. It is caused by the cohesive forces between the molecules of the liquid.

Water:
When a drop of water is placed on a surface, the surface tension of water causes it to form a spherical shape. This shape minimizes the surface area of the water droplet, as the spherical shape has the smallest surface area for a given volume. As a result, the drop of water can move easily on the surface, as there is less friction between the drop and the surface.

Steel Plate or Tiffin Lid:
Both a steel plate and a tiffin lid have smooth surfaces. The smooth surface reduces the friction between the water droplet and the surface, allowing it to move more easily. The water droplet slides and rolls on the surface, making it move faster compared to other substances.

Other Substances:
The other substances mentioned in the options, such as oil, sugar solution, and ghee, have different properties compared to water. They may have different surface tensions or viscosities, which affect their movement on a surface. These substances may not form a spherical shape like water, and their movement may be slower due to higher friction with the surface.

Therefore, when a drop of water is placed on a steel plate or the lid of a tiffin, it will move faster compared to substances like oil, sugar solution, and ghee.
