Answer: Option C. -> Alluvial soil
Alluvial soil is the most ideal for paddy cultivation due to its good water retention capacity and fertility. Alluvial soil is formed due to deposition of silt by rivers. Alluvial soils are found in plains and are generally composed of sand, silt, clay and organic matter. Alluvial soils are the most fertile soils and are considered the best for agriculture. They have high water-holding capacity and are relatively easy to cultivate.

Definition of Alluvial Soil
Alluvial soils are formed by the deposition of sediment by rivers. These soils are mainly composed of sand, silt and clay and are rich in minerals and organic matter. Alluvial soils are usually found in plains and low-lying areas.

Features of Alluvial Soil

The following are the main features of alluvial soil:
High fertility: Alluvial soils are highly fertile due to the presence of minerals, organic matter and clay particles.
Good water retention capacity: Alluvial soils have good water retention capacity due to the presence of clay particles which helps in retaining moisture.
Easy to cultivate: Alluvial soils are relatively easy to cultivate as they are often found in plains and low-lying areas.
High productivity: Alluvial soils are highly productive due to their high fertility and good water retention capacity.

Advantage of Alluvial Soil for Paddy Cultivation
Alluvial soils have high fertility, good water retention capacity and are relatively easy to cultivate which makes them ideal for paddy cultivation.
The presence of clay particles helps in retaining moisture which helps in the growth of the paddy plants.
Alluvial soils have high productivity due to their high fertility and good water retention capacity.
Alluvial soils are also resistant to pests and diseases which helps in preventing crop loss.

Therefore, Alluvial soil is the most ideal for paddy cultivation due to its good water retention capacity, high fertility, and high productivity.
