The three steps from solid to point are
A.Solid-surface-line point
B.Line-point-surface-solid
C.Surface-point-line-solid
D.Point-surface-line-solid

Hint: Here, we will first use a solid that has a shape, size, position and its boundaries are called surfaces and then boundaries of the surface are curves or straight lines to find the required value.

Complete step-by-step answer:
We are given that the three steps are from solid to point.
We know that a solid has a shape, size, position and its boundaries are called surfaces.
The boundaries of the surface are curves or straight lines.
We also know that these lines are points.
So, we have found that we start from solid, then surface and line point in the last.
Therefore, three steps from solid to point are solid-surface-line points.
Hence, option A will be the correct answer.

Note: We know that a closed three-dimensional figure, a solid as any limited portion of space bounded by surfaces. Among the simplest solids are the sphere, cube, cone, cylinder, and more generally, the polyhedral. Also, a surface is the outside layer of an object and a line is defined as a line of points that extends infinitely in two directions. It has one dimension, length.
