Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Indian Agricultural Research Institute and Khadi and Village Industries Commission
Biogas is a mixture of gases, mainly methane, made by methanogens from cattle dung (gobar) in a biogas plant. The technology was developed in India mainly by the Indian Agricultural Research Institute (IARI) and the Khadi and Village Industries Commission (KVIC).
Option (1) Indian Agricultural Research Institute and Khadi and Village Industries Company — Incorrect. The first name is right, but KVIC is a Commission, not a Company. It is a government body that promotes khadi and village industries.
Option (2) Indian Agriculture Research Institute and Khadi and Village Institute Commission — Incorrect. Two words are changed here. The institute is the Indian Agricultural Research Institute, and the commission is of Khadi and Village Industries, not “Institute”.
Option (3) Indian Agricultural Research Institute and Khadi and Village Industries Commission — Correct. Both names are in their full and proper form. Their efforts made biogas plants common in rural areas, where cattle dung is available in large amounts.
Option (4) Indian Agricultural Research Industry and Khadi and Village Industries Commission — Incorrect. The second name is right, but IARI is a research institute, not an industry. It is the “I” for Institute that comes last in IARI.

NCERT Extract:
Microbes in Production of Biogas – “… Cattle dung is available in large quantities in rural areas where cattle are used for a variety of purposes. So biogas plants are more often built in rural areas. The biogas thus produced is used for cooking and lighting. The picture of a biogas plant is shown in Figure 8.8. The technology of biogas production was developed in India mainly due to the efforts of Indian Agricultural Research Institute (IARI) and Khadi and Village Industries Commission (KVIC).”
