Complete Answer:
The technology of biogas production was developed in India mainly by The Indian Agricultural Research Institute (IARI).

So, the correct answer is option (A) i.e, IARI.

Additional information: Stages in biogas production:
Biogas is produced using well-established technology in a process involving various stages:
1) Biowaste is crushed into smaller pieces and slurried to prepare it for the anaerobic digestion process. Slurrifying means adding liquid to the biowaste to make it easier to process.
2) Microbes need warm conditions, so the biowaste is heated to around 37 °C.
3) The main biogas production takes place through anaerobic digestion in the large tanks for about three weeks.
4) In the final stage, the gas is purified by removing the impurities and carbon dioxide.
Then, the biogas becomes ready for use by enterprises and consumers. For example in a liquefied form or following injection into the gas pipeline network

Note: The Indian Agricultural Research Institute (IARI) is also known as the Pusa Institute. It is India's national Institute for agricultural research, education and extension. Currently, the institute is located in Delhi and is financed and administered by the Indian Council of Agricultural Research (ICAR).
