Answer: Choice C
Step-by-step explanation:
Points are locations in space or on a 2D flat plane. Think of an address to a house or perhaps longitude/latitude coordinates. Such locations do not have any width, length or height. There are no dimensions a point. Points are infinitely small. The only reason they appear to have a size is because otherwise we wouldn't be able to see the point locations.
This is why choices A B and D can be ruled out. Only choice C is true.
