The correct option is A.
Explanation
The Peninsular Plateau is a tableland composed of old crystalline, igneous, and metamorphic rocks. It is broadly divided into two regions: the Central Highlands and the Deccan Plateau.- Statement 1 is Correct: The Central Highlands lie to the north of the Narmada river, covering a major area of the Malwa plateau. This region is characterized by being wider in the west (Malwa and Rajasthan side) and becoming progressively narrower towards the east (Bundelkhand and Baghelkhand regions).
- Statement 2 is Correct: The Deccan Plateau is a triangular landmass situated south of the Narmada river. It exhibits a distinct tilt; it is higher in the west and slopes gently towards the east. This structural tilt is the primary reason why major peninsular rivers like the Godavari, Krishna, and Kaveri flow eastward into the Bay of Bengal.
- Statement 3 is Incorrect: The Western Ghats are significantly higher in elevation than the Eastern Ghats. The average elevation of the Western Ghats ranges from 900 to 1,600 metres, whereas the Eastern Ghats average only about 600 metres. Furthermore, the Western Ghats are continuous, while the Eastern Ghats are discontinuous and dissected by rivers.
