Correct answer: (d) Peace
Explanation
- A
Agriculture
There is no Nobel Prize in agriculture as a named category. Borlaug’s wheat work transformed farming, but the award he received was not an agriculture Nobel. This option is not the key.
- B
Economics
The Nobel Memorial Prize in Economic Sciences exists, but Borlaug did not receive it. His citation was humanitarian, not for economic theory. This option is therefore wrong.
- C
Medicine
The Nobel Prize in Physiology or Medicine goes to biomedical discovery. Borlaug was a plant breeder, not a medical laureate. This option is not the key.
- D
Peace
Norman Borlaug received the Nobel Peace Prize in 1970 for the Green Revolution: high-yielding wheat that eased hunger and the social unrest that famine can bring. The Committee treated food security as a path to peace. This option is the official key.
Summary. Official key is (d) Peace. Norman Borlaug, often called the father of the Green Revolution, was awarded the 1970 Nobel Peace Prize, not a prize in agriculture, economics or medicine. There is no Nobel category titled agriculture. His dwarf wheat and related breeding cut famine risk in Mexico, South Asia and beyond. Only (d) matches the actual award.
