Answer 1

The correct option is C Development of new crop varieties which helped to overcome hunger

• The Green Revolution was the notable increase in cereal-grains production in Mexico, India, Pakistan, the Philippines, and other developing countries in the 1960s and 1970s.
• Green revolution was a period when the productivity of global agriculture increased drastically as a result of new advances.
• During this time period, new chemical fertilizers and synthetic herbicides and pesticides were created.
• The chemical fertilizers made it possible, to supply crops with extra nutrients and, therefore, increase yield.
• The newly developed synthetic herbicides and pesticides controlled weeds, deterred or kill insects, and prevented diseases, which also resulted in higher productivity.
• This increase in productivity made it possible to feed the growing human population.
• The extra food produced by the Green Revolution is generally considered to have averted famine in India and Pakistan.

Therefore, the correct answer is option C.
