Answer 1

The correct option is C It is very fertile and supports a wide variety of crops

Laterite soil develops under tropical and subtropical climates with alternate wet and dry seasons. Heavy rainfall causes leaching of silica and lime, while iron oxide and aluminium compounds are left behind.

The soil is deficient in Humus content
and there is a specific reason for it.
Bacterias which thrive well in warm tropical climates are responsible for removing humus from the soil.

Laterite soil is found on hill slopes, which makes it prone to erosion and degradation, and generally not suitable for cultivation.
