Indian States: Physical Divisions Analysis

The question asks to identify an Indian state that possesses all three major types of physical divisions: plateau regions, plains, and coastal plains.

Tamil Nadu's Geography

Let's examine Tamil Nadu:

• Plateau: The state includes parts of the Deccan Plateau. The Western Ghats and the Eastern Ghats mountain ranges run through Tamil Nadu, forming part of this plateau system.
• Plains: Tamil Nadu has significant plains, especially the fertile riverine plains formed by major rivers like the Kaveri (Cauvery). The plains extend inland from the coast.
• Coastal Plains: Situated along the Bay of Bengal, Tamil Nadu has an extensive stretch of coastal plains, particularly the wide coastal region known as the East Coast Plains or the Coromandel Coast.

Therefore, Tamil Nadu exhibits all three required physical divisions.

Analysis of Other States

Madhya Pradesh

Madhya Pradesh is predominantly a plateau state, being a major part of the Malwa Plateau and Vindhya Range. While it has some plains, it lacks significant coastal plains as it is a landlocked state.

Punjab

Punjab is known primarily for the vast, fertile plains of the North Indian River Plains (Indo-Gangetic Plain). It does not have plateau regions or coastal plains.

Uttar Pradesh

Uttar Pradesh is largely covered by the fertile Gangetic Plains. While the southern part includes parts of the Bundelkhand plateau region, it is a landlocked state and does not possess coastal plains.

Based on this geographical analysis, Tamil Nadu is the state that uniquely features plateau, plains, and coastal plains among the given options.
