Answer: C. A plane

Step-by-step explanation:

First we need to know the definition of collinear points.

Collinear points: They are points which can be joined by a single straight line.

For the case of a line segments, all of the points in a line segnment are collinear because we can draw a straight line between them, so this is not the answer.

A line is similar to a line segment, the difference is that the line segment has a definite length. But still in a line we can join the points in it by a straight line, so this is also not the answer.

A ray is mostly used when we talk about light, but in a ray, we can draw a line bewtween points in the ray that are collinear. This is not the answer.

A plane is a two dimensional object, like a wall could be a plane because it has two dimensions lenght and width. You can take three points in a plane and those points can be non-collinear (you could not draw a single straight line between them). This is represented in the image:

In this example of plane we have three non-collinear points.
