Correct option is A
The correct answer is: (a) alluvial soils and high agricultural productivity
Explanation:
The Great Indian Plains, also known as the Indo-Gangetic Plains, are primarily known for their fertile alluvial soils that are deposited by the Ganges, Yamuna, and Brahmaputra rivers.
These soils are highly suitable for agriculture, leading to high agricultural productivity in the region. Major crops such as wheat, rice, sugarcane, and cotton are grown extensively here.
Information Booster:
The alluvial soil is rich in minerals like phosphorus, which supports high crop yields.
The plains are often referred to as the “food bowl of India”.
Indo-Gangetic Plains: This region covers large parts of Punjab, Haryana, Uttar Pradesh, Bihar, and West Bengal.
The region has a high population density, due to its suitability for farming.
