A point or dot is an indicated mark on a flat or sharp-edged surface similar to a round shape in larger scales.
A generalized concept about point in the given selection would be the iris.
The iris refers to the circular colored tissue in the eye that envelopes the pupil and is used to control amount of light perceived in the eye to process vision.
The iris is round and so is the point in larger scales.
Answer: B. Iris
Other selections does not represent point:
- Notebook is in the shape of a rectangle.
- A string is a line.
- A meterstick is also a rectangle and a line. Though, a meterstick might be used to measure distances of coordinates but this case is not indicated in the question.
*Notice how similar the shape of the iris is to the figure on the right. The right-side image is a point.
Disclaimer: Technically speaking, a point does not associate directly with round objects as points have no dimensions if referred or compared to practically with circles having two dimensions. The given explanation should be treated only as a relative generalization.
I hope this helps and you're welcome. Have a nice day learning.
