Hint: Landforms are natural or artificial features of rocky surfaces on Earth. Landforms together make up terrains. The topography is the arrangement of different relief features in a landscape. Landforms are of different types such as canyons, valleys, basins, plateaus, mountains, plains, and peninsulas, etc.

Complete step-by-step solution:
Peninsulas are triangular pieces of land with water on three sides and are connected to the mainland on one side. These are found in every continent.
The peninsular block is formed of ancient granite and gneisses. It is very rigid and stable in its geological structure. The Indian peninsula mostly consists of residual and old fold mountains like the Aravali Hills, the javadi Hills, the velikonda Hills, and the Mahendragiri hills.
The Himalayas are young fold mountains. They have been formed due to the collision of tectonic plates in the very recent past. Hence these are young, weak, and flexible in their geological structure.
The young fold mountains, the Himalayas, and the other Peninsular mountains are continuously subjected to exogenic and endogenic forces. These forces result in the development of fold faults and thrust planes.

Thus, option (C) is correct.

Note: India can be divided into six different physiographic divisions. These are the Northern and North Eastern mountains, North Indian plains or the Northern river Plains of India, the Indian desert, the peninsular plateau, the coastal plains, and the islands. India is often termed as a subcontinent because of its distinct landmass. It is a land full of contrasting relief features, from snow-capped peaks of the Himalayas in the north to tropical evergreen forests of Southern India. The Himalayas and these tropical evergreen forests are biodiversity hotspots in India. They are home to a wide variety of exotic plants and species.
