Assertion: Haryana is a leading state in solar power adoption.
Reason (R): Haryana has vast desert land like Rajasthan suitable for large-scale solar farms.
In the light of the above statements, choose the correct answer from the options given below:

Correct option is C

The correct answer is The correct answer is (c) A is true, R is false
Explanation:
. Assertion (a) is true. Haryana is recognized as a leader in solar power adoption, with high installed capacity and ambitious targets, focusing heavily on rooftop and decentralized solar installations.
. Reason (R) is false. Haryana does not have "vast desert land like Rajasthan". While parts of its southwestern region are semi-arid with sand dunes, it is primarily an agrarian state with limited vacant land for giant solar farms compared to the Thar desert in Rajasthan. Rajasthan is the leading state for large-scale solar farms precisely due to its vast desert terrain.
. Therefore, Assertion A is true, but Reason R is false, as the state's success comes from policy initiatives and rooftop solar, not vast desert land. 
Information Booster:
. Haryana has focused on rooftop solar and decentralized installations because it has less vacant land for giant solar farms.
. Rajasthan utilizes its vast arid land for massive projects like the Bhadla Solar Park, one of the world's largest.
. Haryana's high solar capacity is due to its robust policy support, subsidies for farmers (solar pumps), and mandates for government buildings, rather than natural geography suited for large ground-mounted parks.
