Answer 2

(b) it is rich in iron compounds.

Explanation:

• Red soils develop a reddish colour because of  diffusion of iron in metamorphic and crystalline rocks. It looks yellow when it occurs in a hydrated form
• Red soil is a soil type which develops in a temperate, warm, moist climate under mixed or deciduous forest. They are usually poor growing soils, low in humus and nutrients and tough  to be cultivated due to its low water holding capacity.
