Q1. Which among the following is not an agro-based industry in the state of Rajasthan?

Agro-based industries use agricultural produce as their main raw material. Dal mills depend on pulses, rice mills process paddy, and the cotton industry uses cotton grown in agricultural fields. The iron and steel industry, in contrast, is a mineral- and metal-based industry. It depends on iron ore, coal, limestone and related industrial inputs, not on farm produce. Therefore, among the given choices, iron and steel industry is the one that is not agro-based in Rajasthan.
