Explanation: Uttarakhand, a state in northern India, is renowned for its hilly terrain and is part of the Himalayan mountain range. The state's topography is characterized by high mountains, deep valleys, and dense forests, making it a hilly area. This geographical feature distinguishes it from other states like Rajasthan, Gujarat, and Kerala, which have different topographical features.
Rajasthan, located in the northwestern part of India, is known for its vast deserts, flat plains, and arid landscapes. The topography of Rajasthan is characterized by sand dunes, rocky terrain, and plateaus, which are distinctly different from the hilly terrain of Uttarakhand. The state is famous for its desert regions, such as the Thar Desert, and its historical cities like Jaipur and Jodhpur, which are not associated with hilly areas.
Gujarat, situated in western India, is primarily a coastal state with a mix of plains, deserts, and some low hills. The topography of Gujarat is dominated by the Kutch region and the coastal areas, which do not fit the description of a hilly area. The state is known for its coastal cities like Surat and Ahmedabad, and its desert regions like the Great Rann of Kutch, which are not hilly.
Kerala, located in the southwestern part of India, is known for its coastal plains, backwaters, and some midland and highland regions. While Kerala does have some hills, its topography is not predominantly hilly. The state is more known for its coastal and riverine landscapes, such as the backwaters of Alleppey and the coastal city of Kochi, which are not associated with hilly areas.
In contrast, Uttarakhand's geographical features align with the description of a hilly area. The state is located in the Himalayan region and is characterized by high mountains, deep valleys, and dense forests. The Himalayan range, which dominates the state's topography, includes peaks such as Nanda Devi and Kamet, making Uttarakhand a hilly area. The state is also known for its national parks and wildlife sanctuaries, such as the Jim Corbett National Park and the Valley of Flowers, which are situated in hilly terrains.
Therefore, Uttarakhand is the correct answer as it is a hilly area, characterized by its mountainous and forested landscapes, which are distinct from the topographical features of Rajasthan, Gujarat, and Kerala.
