Consider the following statements regarding Red and Yellow Soils in India: 1. Red soil develops predominantly over crystalline igneous rocks in regions receiving low rainfall. 2. Yellow coloration in soil indicates the presence of iron in a hydrated form. 3. Red and yellow soils are uniformly fertile across both fine-grained and coarse-grained types. Which of the statements given above is/are correct? |ForumIAS

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A

Notes:

Explanation:

Red soil forms over crystalline igneous rocks in areas with low rainfall, especially in parts of the Deccan Plateau.
Yellow soil is essentially hydrated red soil, where iron is in a hydrated form, giving it a yellowish appearance.
Fertility is not uniform—fine-grained soils are fertile, but coarse-grained soils in upland areas are poor in fertility.
