Which of the following statements in respect to the Indian Peninsular Plateau are correct? 1. The Deccan Plateau gradually rises from North to South. 2. The Malwa Plateau dominates the Vindhyan scarps, forming the Eastern flank of the plateau. 3. The Western Satpuras separate the Narmada and Tapi rivers. 4. The Chota Nagpur Plateau is composed of Archaean granite and gneiss rocks. Select the correct answer using the code given below.

The Indian Peninsular Plateau is a complex geological formation. Statement 1 is correct as the Deccan Plateau generally slopes from west to east, but its elevation increases from north to south, particularly along the Western Ghats. Statement 2 is incorrect; the Malwa Plateau is bordered by the Vindhyan Range to the south and the Bundelkhand Plateau to the east, with the Vindhyan scarps forming its southern edge rather than an eastern flank. Statement 3 is correct; the Satpura Range runs parallel to the Vindhyas and acts as a watershed, separating the Narmada river (flowing in the north) from the Tapi river (flowing in the south) [3]. Statement 4 is correct; the Chota Nagpur Plateau is a part of the oldest landmass and is primarily composed of Archaean granite and gneiss rocks, along with Gondwana formations [2].
