Geometry

The answer is A.They lie on the same line.

Analyze each option:

A.They lie on the same line: By the definition of collinear points, if points A, B, and C are collinear, it means they all lie on the same straight line. So this option is correct.

B.They lie on the same plane: While it's true that collinear points also lie on the same plane (since a line is contained within a plane), the more specific and accurate characteristic of collinear points is that they lie on the same line. This option is not the most precise answ...
