The 2014 World Food Prize Laureate, who was honored for his contributions in the field of agriculture, is Sanjaya Rajaram. Option 1, M.S. Swaminathan, is not the correct answer, as M.S. Swaminathan is a renowned Indian geneticist and agricultural scientist who is often referred to as the "Father of the Green Revolution in India." Although he has made significant contributions to the field of agriculture, he was not honored as the 2014 World Food Prize Laureate. Option 3, Hari Shankar Gupta, is not the correct answer either, as there is no notable information available about this individual and their contributions to agriculture. Option 4, C.N.R. Rao, is also an incorrect answer, as C.N.R. Rao is an Indian chemist and professor who has made remarkable contributions to the field of solid-state and structural chemistry, but not specifically in the realm of food production or agriculture. Therefore, the correct answer is option 2, Sanjaya Rajaram.
