Answer:
D. Line segment
Step-by-step explanation:
We are required to find the geometric shape having fixed distance along a line.
Since, an angle and a point cannot have fixed distance along a line.
Options A and B are discarded.
Further, as skew lines are the lines which do not intersect and are not parallel.
Thus, they may or may not have fixed distance along a line.
Thus, option C is not correct.
Hence, option D i.e. a line segment, which will have fixed distance along the line is correct.
