Hint: Semi-dwarf wheat is the dominant wheat variety currently grown, accounting for approximately 99 percent of global wheat acreage. It was developed in Mexico in the mid-1940s-50s as a means of growing the yield of wheat and making the country more self-sufficient in food production.

Complete Answer:
- It was founded in Mexico in the mid-1940s-50s by Dr. Norman Borlaug, geneticist, plant pathologist and Nobel Peace Prize laureate. Borlaug directed the Cooperative Wheat Research and Development Program in Mexico, a joint venture between the Mexican government and the United States. Rockefeller Organization, please.
- He and his team were successful in finding a high-yield, short-strung, disease-resistant wheat that was suited to local conditions.
- Borlaug started to cross Vogel's semi-dwarf varieties with Mexican varieties in 1953. A new form of spring wheat resulted: short and stiff-strawed varieties that tilled abundantly, produced more grain per head and were less likely to lodge.
- The semi-dwarf Mexican wheat offspring started to be spread nationally after a series of crosses and re-crosses, and average wheat yields in Mexico doubled within 7 years.
- Compared to normal wheat, which is tall and wavy, this wheat has several benefits. The above blows in the wind, and the plant will fall over if grains at the top of the plant get too high. The plant becomes unusable once grain heads hit the earth.
- Semi-dwarf wheat is a shorter plant that does not fall over in the wind or if the head of the grain gets heavy with a stronger stalk.
- The plant also needs less time to expand to the height required to produce grain. Plus, mixtures and other heavy machinery will harvest the shorter, harder stalk, making wheat harvesting less labour-intensive. In addition, the variety of Borlaug is resistant to wheat rust (except for today's latest strain called 'Ug99') and can withstand heavy quantities of fertilizer.

The correct answer is option(C) Norman Borlaug.

Note: Two of the most popular Sonora 64 and Lerma Rojo 64 varieties were called by Borlaug, and these two varieties contributed to the Green Revolution in India, Pakistan and other countries. Hundreds of millions of people were gradually saved from hunger by this foreign exchange of ideas and germplasm, beginning with genetic capital from Japan.
