The correct answer is: B. rich, muddy and saturated with water.
Rice is a semiaquatic plant that grows best in flooded soils. The ideal soil for rice is a rich, muddy loam that is saturated with water. This type of soil provides the nutrients and moisture that rice plants need to thrive.
Clayey loam is a type of soil that is composed of a mixture of clay, silt, and sand. Clayey loams are typically rich in nutrients and have good drainage. However, they can be too heavy for rice plants to grow in.
Deep, loamy, well drained soil is a good type of soil for many plants, but it is not ideal for rice. Rice plants need to grow in flooded soils, so deep, loamy, well drained soil will not provide the necessary moisture.
Humus, rich in Fe and potash is a type of soil that is high in organic matter. Organic matter helps to improve soil structure and drainage. However, it does not provide the nutrients and moisture that rice plants need to thrive.
Therefore, the best type of soil for rice is a rich, muddy loam that is saturated with water.
