Question

# Image represents a line.

Hint:

## The correct answer is:

### A line is a one-dimensional geometric figure that has only length but no width and height. Basically, a line is made up of a set of infinite points and it is extended towards infinity in both the directions. It can be determined by two points in two-dimensional plane. If we fixed two points on a line, then the part of the line between those two points is called a line segment. For example, consider the following figure:Here, the first one is a line whereas the second one is a line segment situated between two points on a line.Again, a ray is a part of a straight line that has one fixed point but the other point does not have an end i.e., a ray has one terminating end but the other end is extending infinitely. For example, consider the following figure:In the above figure,  is a ray, where  is the fixed end point and the other point  is extending infinitely i.e., one terminating point is symbolized as  and the infinitely extending part is depicted by an arrow.Now, the given figures are:Clearly, this is a ray as it has one end point fixed and the other part is extending to infinity.By definition, it is a line segment as both of its end points are fixed.Clearly, this is a line as it is extending towards infinity in both the directions.Again, this is a ray.Therefore, the image that represents a line is:  .

Note that a straight line is extended to infinity in both the directions whereas a ray has one end point fixed and the other part is extending infinitely and a line segment has two end points fixed on a straight line.
