Q1. Indira Gandhi Nahar Project is better known as the lifeline of which region? Choose the most appropriate option from the following.
Explanation
Indira Gandhi Nahar Project is called the lifeline of Western Rajasthan because it carries canal water into the arid districts of the Thar region, supporting drinking water, irrigation and settlement. Eastern Rajasthan has comparatively better rainfall and a different river system, so the phrase is not attached to it. Northern Rajasthan benefits in parts, but the standard description refers to the western desert belt. Southern Rajasthan has the Aravalli and tribal upland context, not the IGNP lifeline identity.
