Solution
The correct option is B Laterite Laterite is a soil layer, that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions, where the climate is humid. When the velocity of running water decreases the heaviest particles are deposited on a riverbed. The finest particles (gravel, silt, sand, and clay) are deposited at the mouth of the river, forming a delta made of alluvial soil.
Loam is soil composed mostly of sand and silt, and a smaller amount of clay.
