The question asks which statement about India`s ranking in various global industries is not correct.

Option 1 asserts that India is the second largest producer of nitrogenous fertilisers in the world. This statement is identified as the correct answer, which indicates it is not correct – perhaps India`s ranking is not second in terms of nitrogenous fertilisers production, or it could be ranked elsewhere.

Option 2 places India as the ninth-largest steel producing country in the world. This indicates that eight other countries produce more steel than India.

Option 3 says that India is the second-largest producer of silk in the world. This suggests that only one other country produces more silk than India.

Lastly, Option 4 claims that India ranks third in the world in coal production, indicating that only two countries produce more coal.

The options attempt to provide a comparative placement of India in several worldwide industries, and the correctness hinges on the actual global production and India’s specific production in these areas.
