The correct answer is Thar.
The Thar Desert, also known as the Great Indian Desert, is located in the northwestern part of India. It's a large, arid region that spans across parts of India and Pakistan. The Thar Desert is characterized by its sandy landscape, sparse vegetation, and extreme temperatures. It's a significant geographical feature of the region, playing a role in the climate and ecology of northwestern India. The other options, Deccan, Ghat, and Malva, refer to different geographical regions in India, but they are not deserts located in the northwest. The Deccan Plateau is a large plateau in southern India, the Ghats are mountain ranges along India's western and eastern coasts, and Malva is a plateau region in central India. Therefore, only the Thar Desert fits the description of a desert located in northwestern India.
