The correct answer is C. Aravalli Rehabilitation Scheme.
The Aravalli Rehabilitation Scheme was launched in 1995 by the Government of Haryana to rehabilitate the Aravalli hills, which are a major source of water and livelihood for the people of the state. The scheme aims to plant trees on open and rocky land in the Aravalli hills, to prevent soil erosion and improve the environment.
The Jawaharlal Project is a national project that aims to develop the arid and semi-arid regions of India. The Desert Development Project is a national project that aims to develop the desert areas of India. The Fodder Scheme is a national scheme that aims to provide fodder for livestock.
The Aravalli Rehabilitation Scheme is the only scheme that specifically aims to plant trees on open and rocky land in the Aravalli hills. The other schemes are not relevant to the question.
