Answer: Option B

Solution(By Examveda Team)

Andisols are derived from volcanic ejecta and are dominated by allophane.
Andisols are an essential tool for agriculture and can be used to cultivate sugarcane, tobacco, potatoes, tea, vegetables, wheat, rice and other crops. These soils also sustain fragile ecosystems in the Andes mountains from forests to paramos, helping to provide essential nutrients and regulate the water cycle.
