The biggest LNG supplier to India is

Iran
Kuwait
Qatar
Saudi Arabia

The correct answer is (c). Qatar is the biggest LNG supplier to India.

Qatar is the world’s largest LNG exporter, and India is the world’s third-largest LNG importer. Qatar supplies about 20% of India’s LNG imports.

Iran, Kuwait, and Saudi Arabia are also major LNG producers, but they do not export as much LNG to India as Qatar does.

Iran is currently under US sanctions, which has limited its ability to export LNG. Kuwait and Saudi Arabia have both increased their LNG exports in recent years, but they still do not export as much LNG to India as Qatar does.

Qatar has a number of advantages over other LNG producers, including its large reserves of natural gas, its proximity to India, and its well-developed LNG infrastructure.

Qatar has the world’s third-largest proven natural gas reserves, after Russia and Iran. Qatar’s natural gas reserves are located in the North Field, which is the world’s largest natural gas field.

Qatar is located just across the Arabian Sea from India. This proximity makes it easier and cheaper for Qatar to export LNG to India than it is for other LNG producers.

Qatar has a well-developed LNG infrastructure, including three LNG liquefaction plants and a network of pipelines. This infrastructure allows Qatar to export LNG to India and other markets around the world.

In conclusion, Qatar is the biggest LNG supplier to India because of its large reserves of natural gas, its proximity to India, and its well-developed LNG infrastructure.
