In India, the steel production industry requires the import of
A
saltpetre
B
rock phosphate
C
coking coal
Correct Answer
D
All of the above
Explanation
India imports coking coal because its domestic reserves are high in ash content and unsuitable for the metallurgical process required to convert iron ore into steel. Option (d) is incorrect because saltpetre and rock phosphate are primarily used in the fertilizer and chemical industries, not as essential raw materials for steel manufacturing. The core concept being tested is the geographical distribution of industrial raw materials and India's specific resource deficiencies in the heavy industry sector.
