Which one of the following is a part of Deccan Plateau?

The Peninsular Plateau of India is divided into several sub-regions, including the Central Highlands and the Deccan Plateau. While the Aravalli and Vindhyan Hills are part of the Central Highlands [2], the Karbi Anglong Hills represent a northeastern extension of the Peninsular Plateau [3]. Specifically, the Deccan Plateau is higher in the west and slopes eastwards, but its geological extension is visible in the northeast as the Meghalaya Plateau, Karbi Anglong Plateau, and North Cachar Hills [1]. These are separated from the main Chotanagpur Plateau by a fault [1]. In contrast, the Shivalik Hills are the outermost range of the Himalayas and are not part of the Peninsular block. Therefore, among the given options, the Karbi Anglong Hills are geologically part of the same ancient landmass as the Deccan Plateau [3].
