Explanation:

• Methane hydrates consist of molecules of natural gas (the chief constituent of natural gas; methane) enclosed within a solid lattice of water molecules. When brought to the earth’s surface, one cubic meter of gas hydrate releases 164 cubic meters of natural gas.
• Gas hydrate deposits are found wherever methane occurs in the presence of water under elevated pressures and at relatively low temperatures, such as beneath permafrost or in shallow sediments along deepwater continental margins.
• In a recent study conducted by researchers at the Agharkar Research Institute (ARI), an autonomous institute of the Department of Science and Technology, have found that the methane hydrate deposits are located in the Krishna-Godavari (KG) basin are of biogenic origin.

Hence both statements are correct.
