The following are the major oilseeds produced in India:

Correct Option

The correct descending order of oilseed production in India, based on the period relevant to the question, is Groundnut, followed by Soyabean, then Mustard, and finally Sesamum. This sequence corresponds to 3, 4, 2, 1.

• Groundnut (3) has historically been the largest oilseed crop in India, with significant cultivation in states such as Gujarat, Andhra Pradesh, and Tamil Nadu.
• Soyabean (4) emerged as the second most produced oilseed, primarily grown in Madhya Pradesh and Maharashtra.
• Mustard (2) ranks third in production among these four, with its main growing regions being Rajasthan, Haryana, and Uttar Pradesh.
• Sesamum (1), while an important traditional oilseed, has a comparatively lower overall production volume among the listed crops, cultivated in states like West Bengal, Odisha, and parts of Andhra Pradesh.

Incorrect Options

Option (a) 1, 2, 3, 4 is incorrect because Sesamum (1) has the lowest production among the four oilseeds listed, not the highest.

Option (b) 3, 2, 4, 1 is incorrect as it places Mustard (2) before Soyabean (4). Actual production data indicates Soyabean production generally exceeds that of Mustard.

Option (c) 2, 4, 3, 1 is incorrect because Mustard (2) does not precede Groundnut (3) or Soyabean (4) in terms of total production volume.
