RAS question
Rajasthan is the largest producer of which mineral in India?
Correct answer: (B) Marble.
Rajasthan is India's largest producer of marble, accounting for about 90% of the country's marble output.
Explanation
Rajasthan is the answer because marble is the mineral in the options for which the state has a clearly dominant national position. Rajasthan produces about 90% of India's marble, with major deposits in Makrana, Rajsamand and Udaipur. Rising Rajasthan - Mines and Minerals identifies Rajasthan as the greatest producer of marble and places marble alongside the state's broader mineral strengths. For an RAS economy question, the key is not just that Rajasthan has marble deposits, but that its share is large enough to make it the leading producer in India.
Why the other options are wrong
- (A) Bauxite is not the mineral for which Rajasthan is India's largest producer.
- (C) Iron ore is discussed in the broader India-level mining context, but Rajasthan's stated leading mineral among the options is marble.
- (D) Coal is mentioned in relation to India's wider mineral profile, not as a Rajasthan mineral in which the state leads the country.
Concept
This tests Rajasthan's mineral economy, especially the state's nationally dominant mineral outputs. Such questions recur in RAS because minerals link geography, regional industry and state economic planning.
