Q1. Which is the oldest public sector undertaking of Rajasthan? Choose the most appropriate option from the following.
A Hindustan Salts Ltd.
B Rajasthan State Ganganagar Sugar Mills Limited Correct
C Rajasthan Drugs and Pharmaceuticals Ltd.
D Rajasthan Electronics and Instruments Ltd.
Explanation
Rajasthan State Ganganagar Sugar Mills Limited is treated as the oldest public sector undertaking associated with Rajasthan, so it matches the official key. Hindustan Salts Ltd. is an older salt-sector company, but it is not the Rajasthan state undertaking asked for here. Rajasthan Drugs and Pharmaceuticals Ltd. came later in the pharmaceutical sector, and Rajasthan Electronics and Instruments Ltd. belongs to the electronics and instrumentation sector. The question asks specifically for the oldest public sector undertaking of Rajasthan, not for the oldest company among all names listed.
