Deserts, fertile plains and moderately forested mountains are the characteristic features of which one of the following regions of India ?

The North-Western region of India is uniquely characterized by the coexistence of deserts, fertile plains, and moderately forested mountains. The Thar Desert, covering over 200,000 sq km primarily in Rajasthan, represents the arid desert component [1]. Adjacent to this are the fertile plains of Punjab and Haryana, which form part of the Indo-Gangetic Plain created by the Indus and Ganga river systems [3]. The region also features the Aravalli Range, one of the world's oldest fold mountains, which are described as highly denuded and moderately forested compared to the dense tropical forests of the south or the alpine vegetation of the north. In contrast, the South-Western border and Coromandel Coast are dominated by coastal strips and ghats [2], while the North-Eastern Frontier is characterized by high-rainfall rugged mountains and deep gorges rather than expansive deserts [3].
