Answer 2

The correct solution parameter in the given question is Height, Spacing, and form of irregularities (option 4).

• The amount of small or coarse irregularities created from a flat plane determines the roughness of a surface.
• It gives any surface its texture.
• However, while determining the roughness of a surface, it is necessary to account for all dimensions of irregularities as well as the distance between them.
• The size or extent and shape of the irregularity must be evaluated.
• This has an effect on the height of the surface irregularity.
• In addition, the space between all of the irregularities must be considered, as it differs depending on the type or form of surface.
• As a result, all of the criteria are crucial in determining roughness.
