Explanation

The correct answer is A because of the following reasons: Statement 1 is correct. Liquefied Natural Gas is produced by cooling natural gas to approximately minus 162 degrees Celsius. This process, combined with pressure management, reduces its volume by about 600 times, making it efficient to transport in specialized cryogenic tankers. Statement 2 is incorrect. India first LNG terminal was commissioned in 2004 at Dahej in Gujarat, operated by Petronet LNG. Hassan is located in Karnataka and is known for being a key point in gas pipelines, but it did not host the first LNG terminal. Statement 3 is incorrect. Natural Gas Liquids are components of natural gas that are separated from the gaseous state, not from LPG. While they do include ethane, propane, and butane, they are extracted during the processing of wellhead natural gas. In fact, LPG itself is typically made up of propane and butane derived from NGLs or oil refining.
