The region characterized by deserts, fertile plains, and moderately forested mountains is North-Western India.
North-Western India includes the states of Rajasthan (home to the Thar Desert), Punjab and Haryana (part of the fertile Indo-Gangetic plains), and parts of the Himalayan and Aravalli ranges (moderately forested mountains). This combination of diverse geographical features makes North-Western India unique in having all three characteristics.
Other options do not fit this description: The South-Western border along the Arabian Sea includes coastal plains and the Western Ghats (dense forests and hills) but no deserts. The Coromandel Coast includes coastal plains, fertile delta regions, and the Eastern Ghats (hills/mountains) but no deserts. The North-Eastern Frontier is predominantly mountainous and hilly with dense forests and fertile valleys, but no deserts.
