Dark matter
absorb light,
emit radiation, and

The correct answer from the list is: none of the above.
The correct answer is: Dark matter does not absorb light, does not emit radiation, and has not been observed directly.
To answer this question, we need to understand the properties of dark matter. Dark matter is a hypothetical form of matter that is thought to make up a significant portion of the total mass in the universe. It is called "dark" because it does not interact with electromagnetic radiation, such as light, which makes it difficult to observe directly.
Based on this information, we can eliminate the options that involve interacting with light. Dark matter does not absorb light because it does not interact with it. It also does not emit radiation directly because it does not have any electromagnetic interactions.
Therefore, the correct answer would be "has not been observed directly." Dark matter has been inferred through its gravitational effects on visible matter, but it has not been directly observed or detected in a laboratory setting.
