While non-metals themselves generally do not react with water to produce oxides, their oxides (non-metal oxides) are typically acidic oxides. When these acidic oxides dissolve in water, they react to form acidic solutions. For example, CO2 dissolves in water to form carbonic acid, SO2 forms sulfurous acid, and SO3 forms sulfuric acid. Thus, non-metal oxides are characterized as producing acidic solutions when dissolved in water.

Oxides are classified as acidic, basic, amphoteric, or neutral. Non-metal oxides generally react with water to form acids, classifying them as acidic oxides. Metal oxides, in contrast, generally react with water to form bases, classifying them as basic oxides.

Some non-metals like chlorine react with water in a redox process (disproportionation) to form acidic solutions (HCl and HOCl). However, the options provided relate to oxides and hydroxides. The most common and general property associated with non-metals in this context (especially when contrasted with metals forming basic oxides/hydroxides) is the acidic nature of their oxides and the resulting solutions when these oxides dissolve in water.
