India continues to be dependent on imports to meet the requirement of oilseeds in the country because:
1. farmers prefer to grow food grains with highly remunerative support prices.
2. most of the cultivation of oilseed crops continues to be dependent on rainfall.
3. oils from the seeds of tree origin and rice bran have remained unexploited.
4. it is far cheaper to import oilseeds than to cultivate the oilseed crops.
Which of the statements given above are correct?
