Correct Option (d)
Explanation
Statement 1 is incorrect.
- Coalbed methane (CBM) is primarily methane (CH₄) gas that is adsorbed within coal seams. It is extracted directly from these coal deposits.
- Shale gas is also predominantly methane, which is trapped within the pores of fine-grained sedimentary rocks known as shale formations. It is not solely a mixture of propane and butane.
Statement 2 is incorrect.
- India possesses significant coalbed methane (CBM) reserves, and commercial production of CBM is ongoing in various blocks across the country.
- Contrary to the statement, India has identified several potential shale gas basins. These include the Cambay Basin (Gujarat), Krishna-Godavari Basin (Andhra Pradesh), Cauvery Basin (Tamil Nadu), and certain Gondwana basins. Exploratory activities for shale gas have been initiated by public sector undertakings like ONGC and OIL.
Since both Statement 1 and Statement 2 are factually incorrect, the correct option is (d) Neither 1 nor 2.
Incorrect Options
- Option (a) is incorrect because Statement 1 is false.
- Option (b) is incorrect because Statement 2 is false.
- Option (c) is incorrect because both Statement 1 and Statement 2 are false.
