Step 1: Understanding the Concept:
This matching question covers the geographical distribution of major agricultural and horticultural crops in India, identifying the leading state for each crop's production.
Step 2: Detailed Explanation:
Let us match each crop with its primary producing state based on national agricultural statistics:
(A) Cotton:
Maharashtra is a leading producer of cotton in India, utilizing extensive black cotton soils (vertisols) in the Deccan plateau.
Hence, (A) matches with (IV).
(B) Mustard:
Rajasthan is the leading state for rapeseed and mustard production in India, accounting for nearly half of the national output due to its dry, temperate winter climate.
Hence, (B) matches with (III).
(C) Potato:
Uttar Pradesh is the leading producer of potatoes in India, utilizing the fertile alluvial soils of the Indo-Gangetic plains.
Hence, (C) matches with (I).
(D) Redgram (Pigeonpea):
Karnataka is a major producer of redgram (pigeonpea) in India, particularly in the northern dry districts like Kalaburagi, which is known as the "pulse bowl" of the state.
Hence, (D) matches with (II).
Step 3: Final Answer:
The correct matching sequence is:
(A) - (IV), (B) - (III), (C) - (I), (D) - (II).
This corresponds to Option (C).
