| Husband-Wife Team | Award |
|---|---|
| 1. Bill and Melinda Gates | i. Right to Livelihood Award |
| 2. Sankaralingam and Krishnammal | ii. UN Population Award |
| 3. Prakash and Mandakini Amte | iii. Kyoto Prize |
| 4. Peter and Rosemary Grant | iv. Magsaysay Award |
Working through each pair separately makes the correct combination clear. Bill and Melinda Gates, through their foundation's large scale funding of global health and population programmes, are linked to the UN Population Award. Sankaralingam Jagannathan and Krishnammal Jagannathan, longtime Gandhian activists who fought for land rights of landless labourers in Tamil Nadu, hold the Right to Livelihood Award, sometimes called the alternative Nobel. Prakash Amte and Mandakini Amte, who took forward the work started by Baba Amte among the Madia Gond community at Hemalkasa, were honoured jointly with the Ramon Magsaysay Award in 2008. Peter and Rosemary Grant, biologists known for their long running research on Darwin's finches in the Galapagos, received the Kyoto Prize in the basic sciences category in 2009.
Putting these together gives 1 with ii, 2 with i, 3 with iv, and 4 with iii, which is option 2. Any option that swaps the Amtes' Magsaysay Award with the Grants' Kyoto Prize, or otherwise rearranges these pairs, does not match the real record of who won what. The correct sequence is 1-ii, 2-i, 3-iv, 4-iii.
