Most metals form basic oxides. However, some metals like aluminium and zinc, are amphoteric and form basic as well as acidic oxides. Non-metals react with oxygen to form acidic oxides or neutral oxides. E.g. Hydrogen forms a neutral oxide - H2O.

Statement A: All metals form basic oxides.
Statement B: Few non-metals form neutral oxides.
Explanation:
Statement A: All metals form basic oxides.
- This statement is true. When metals combine with oxygen, they form metal oxides. These metal oxides are generally basic in nature because they react with water to form metal hydroxides which are alkaline in nature. For example, when sodium (a metal) reacts with oxygen, it forms sodium oxide (Na2O) which reacts with water to form sodium hydroxide (NaOH), a strong base.
Statement B: Few non-metals form neutral oxides.
- This statement is false. Non-metals generally form acidic or neutral oxides. Acidic oxides are formed when non-metals combine with oxygen to form oxides that react with water to produce acids. For example, sulfur (a non-metal) combines with oxygen to form sulfur dioxide (SO2), which dissolves in water to form sulfurous acid (H2SO3). Neutral oxides, on the other hand, are formed when non-metals combine with oxygen to form oxides that do not react with water to produce acids or bases. For example, carbon (a non-metal) combines with oxygen to form carbon dioxide (CO2), which does not react with water to produce an acid or a base.
Therefore, both Statement A and Statement B are not true.
The correct answer is option B - Statement A is false.
