Given below are two statements:
Statement I: The area north of Narmada Son Trough is the chief wheat producer of India.
Statement II: Of the total area under rice in Assam, 90% is irrigated.
In the light of the above statements, choose the correct answer from the options given below:

Correct option is C

The correct answer is The correct answer is (c) Statement I is true but Statement II is false 
Explanation:
. Statement I is true; the major wheat-producing region of India comprises the Indo-Gangetic plain, which is predominantly located north of the Narmada-Son Trough (this includes Punjab, Haryana, Uttar Pradesh, and parts of Madhya Pradesh, which is north of the Narmada river).
. Statement II is false; a significant portion of rice cultivation in Assam relies heavily on rainfall (rainfed agriculture) due to the region's high rainfall. The percentage of irrigated rice area is much lower than 90%. Official statistics show that only a fraction of the total cultivated area in Assam is irrigated (often cited around 10-15% of net sown area or similar low figures, not 90% of rice area). 
Information Booster:
. Wheat is primarily a rabi (winter) crop, requiring cooler temperatures during growth and bright sunshine at the time of harvest.
. Rice is a kharif (monsoon) crop in Assam (called 'ahu', 'sali', and 'boro' rice based on seasons), and is well-suited to the high rainfall and alluvial soil of the Brahmaputra valley.
. The Green Revolution significantly boosted wheat production in the northern states of Punjab and Haryana due to the package of HYV seeds and irrigation.
