The Peninsular Plateau is made of old igneous and metamorphic rocks. For exams remember it as a stable block.

Malwa Plateau is an important part of the Central Highlands. For exams remember the plateau region north of Narmada.

Because of the eastward slope of Deccan Plateau many major rivers flow east. For exams remember Godavari Krishna Kaveri.

In the Deccan Trap black soil forms from weathered lava rocks. For exams remember the black soil and cotton link.

Mineral wealth is common in ancient rocky plateau regions. For exams remember Chotanagpur as a mineral region.

Meghalaya Plateau is a northeastern extension of the Peninsular Plateau but appears separated by plains. For exams remember Garo Khasi Jaintia.

Moist winds rising after hitting mountains cause orographic rainfall. For exams remember windward slope.

The Rann of Kachchh and the Thar Desert are both dry-region landscapes, but their surfaces and physical conditions are different. The Rann is a very low-lying saline marsh or salt-encrusted plain that may experience seasonal inundation. The Thar is chiefly a sandy desert with dunes, loose sand, and arid conditions. Their climates and ecosystems are also influenced by these contrasting landforms and water conditions.

Option A is correct because it clearly states this distinction: the Rann is a saline marshy plain, whereas the Thar is a sandy desert. The Rann is not a glacial area, a black-soil plateau, or the delta of the Ganga. Those alternatives describe unrelated physical features. Remembering Gujarat and salt for the Rann, and sand and dunes for the Thar, helps avoid confusion between them.

Western Ghats are close to the Arabian Sea so the western coast is narrow. For exams remember the coast comparison.

Mahanadi Godavari Krishna and Kaveri form deltas on the eastern coast. For exams remember the Bay of Bengal.
