Answer 1

Hint A crop is a plant or a plant product that can be grown and harvested for profit or subsistence. Based on use crops fall into 6 types: food crops, feed crops, fibre crops, oil crops, ornamental crops, and industrial crops. The top five crops in the world according to annual production are Potato, wheat, rice, corn, and barley.
Complete Step-by-step answer:

The world’s top four food-producing countries are China, India, the U.S., and brazil. They are the largest producer of food as these countries have large population sizes, plenty of lands and the climate is also suitable for growing a variety of crops. But there are also major differences in the role that food production plays in their economy.
The top five crops in terms of annual production from the family Poaceae are wheat i.e., Triticum aestivum , corn i.e., Zea mays, rice i.e., Oryza sativa and barley Hordeum vulagare and from the family Solanaceae is potato i.e., Solanum tuberrosum.
Hence the correct answer is option C.
Note: India is mainly an agriculture-based country. Agriculture accounts for approximately 33% of the GDP of India. The development of many high-yielding varieties of wheat and rice in the mid-1960s, as a result of various plant breeding techniques, led to dramatic increases in food production in our country. This is called the green revolution. Crops included are wheat and rice, sugarcane, and millet.
