Plants like sunflower, brassica, apple and pears are generally pollinated by
1 Wind
2 Bees
3 Butterflies
4 Birds
Explanation:
Bees are pollinators of many of crop species such as Sunflower, Brassica, apple and pear. Keeping beehives in crop fields during flowering period increases pollination efficiency and improves yield.

Assertion : Use of fertilizers greatly enhances crop productivity. Reason : Irrigation is very important in increasing crop productivity
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Irrigation relates to the supply of water to the crops. Fertilizers which are mainly NPK are required to increase the harvest of crops.

Assertion : Emasculation is the process of removal of pistils from bisexual flowers. Reason : Emasculation is used in biotechnology.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Emasculation process in which female flowers are opened in bud condition and their anthers are removed carefully. It checks the chances of self pollination. Pollen grains are also killed in such flowers by dipping in water at \(500 \mathrm{C}\) for ten minutes, or spraying with inhibitor like malefic hydrazine.
