The process of decay of organic matter produces carbonic acid which dissolves minerals more rapidly is called

Correct option is B

During the decomposition of organic matter, large amounts of carbon dioxide are released into the soil. This carbon dioxide reacts with soil water to form carbonic acid, a weak acid capable of dissolving minerals. The presence of carbonic acid accelerates chemical weathering of soil minerals, especially carbonates. This weathering process is known as carbonation.
Information booster: Carbonation is one of the major chemical weathering processes involved in soil formation. It is most effective in humid regions where moisture and organic matter decomposition are high. Carbonation leads to leaching of basic cations such as calcium and magnesium from the soil. This process plays an important role in soil profile development and nutrient transformation.
Why other options are incorrect: (a) Hydrolysis involves reaction of minerals with water without carbonic acid formation. (c) Hydration refers to physical absorption of water by minerals. (d) Oxidation involves reaction with oxygen and is unrelated to carbonic acid action.
