Other options are incorrect because
Point is small representation of anything that this universe has got.Consider trees, yourself, bulb,...if you consider all these things with respect to earth these are points.Stars, planets all are points in the space when we look from the earth.
A line is formed when we join any two points in a plane. Consider two things in your room like two chairs.Mark circles to represent chairs.A line is formed.
