The correct characteristics of dark matter are:

  1. Does not interact with baryonic matter - Dark matter does not interact in the same way as normal matter, which is composed of protons, neutrons, and electrons.

  2. Does not interact with electromagnetic radiation - Dark matter does not emit, absorb, or reflect light, which is why it is "dark" and cannot be seen directly.

  3. Has not been directly observed - While dark matter's existence is inferred from gravitational effects, it has not been observed directly.

The first response (has been directly observed) is incorrect, so it should not be selected.
