While researching a topic, a student has taken the following notes:

Question

Haidinger's brush is an entoptic phenomenon, meaning a visual effect that is produced by the human eye rather than originating from an outside light source.
It appears as a very faint yellow and blue pattern when looking at a blank white field or a clear blue sky.
The pattern is due to the interaction of linearly polarized light with the human eye's cornea and lens.
It is named after Austrian physicist Wilhelm Karl von Haidinger, who first described it in 1844.
Seeing Haidinger's brush is an indication of good eye health, as certain eye conditions like macular degeneration can prevent people from perceiving it.
The student wants to explain how perceiving Haidinger’s brush relates to eye health. Which choice most effectively uses relevant information from the notes to accomplish this goal?

(Choice A) Haidinger's brush, first described by Austrian physicist Wilhelm Karl von Haidinger in 1844, appears to the eye as a faint yellow and blue pattern when looking at a blank white field or a clear blue sky.
A
Haidinger's brush, first described by Austrian physicist Wilhelm Karl von Haidinger in 1844, appears to the eye as a faint yellow and blue pattern when looking at a blank white field or a clear blue sky.
(Choice B) The faint yellow and blue pattern known as Haidinger's brush is an entoptic phenomenon caused by the interaction of linearly polarized light with the cornea and lens of the human eye.
B
The faint yellow and blue pattern known as Haidinger's brush is an entoptic phenomenon caused by the interaction of linearly polarized light with the cornea and lens of the human eye.
(Choice C) Seeing Haidinger’s brush—an entoptic visual effect produced by the interaction of linearly polarized light with the cornea and lens of the human eye—indicates good eye health, since conditions like macular degeneration can prevent its perception.
C
Seeing Haidinger’s brush—an entoptic visual effect produced by the interaction of linearly polarized light with the cornea and lens of the human eye—indicates good eye health, since conditions like macular degeneration can prevent its perception.
(Choice D) Named after Wilhelm Karl von Haidinger, Haidinger’s brush is a faint pattern that can be seen when looking at a clear sky, and it is an indication of good eye health.
D
Named after Wilhelm Karl von Haidinger, Haidinger’s brush is a faint pattern that can be seen when looking at a clear sky, and it is an indication of good eye health.
which is the true correct answer a b c or d

Answer 1

The choice that most effectively explains how perceiving Haidinger's brush relates to eye health is:

(Choice C) Seeing Haidinger’s brush—an entoptic visual effect produced by the interaction of linearly polarized light with the cornea and lens of the human eye—indicates good eye health, since conditions like macular degeneration can prevent its perception.

This choice includes relevant information about what Haidinger's brush is, how it is produced, and clearly ties its perception to good eye health by mentioning conditions that can prevent seeing it.
