Q1. Which is the correct pair of major mustard-producing districts of Rajasthan?
Explanation
Alwar and Jaipur are recognised as major mustard-producing districts in Rajasthan, so this pair matches the published key. Ajmer and Nagaur are important agricultural districts but are not the best pair for the major mustard belt asked here. Bikaner and Jaisalmer are more strongly associated with arid western Rajasthan and do not form the main mustard-producing pair. Karauli and Sawai Madhopur grow crops in eastern Rajasthan, but they are not the standard leading pair for mustard in this question.
