Explanation:

Gases have particles that are widely spaced, meaning there are very few molecules in a given volume to interact with or reflect light, making them hard to see. The first option describes the particle arrangement of solids/liquids, not gases.

Answer:

Moleuces are further apart (note: this contains a typo, it should be "Molecules are further apart")
