Explanation:

- Metal oxides are generally basic in nature.

- When metal oxides react with water, they form metal hydroxides, which are basic.

- They can neutralize acids to form salt and water.

- Option 1: Acidic

- Acidic oxides usually come from nonmetals. They react with bases to form salt and water.

- Option 2: Organic

- Metal oxides are inorganic, not organic. This term is unrelated to their chemical nature.

- Option 3: Neutral

- Neutral oxides do not react with acids or bases. Examples include some rare examples like nitrous oxide.

- Option 4: Basic

- Most metal oxides, like calcium oxide or magnesium oxide, display basic properties.
