Which option keeps both sea relation and relief type correct among India's physiographic divisions?

Correct answer: Coastal Plains are level land along the sea

The direct answer is A: coastal plains are level land along the sea. A physiographic division describes a broad landform, while a sea relation tells us where that landform lies. Coastal plains are low, relatively level strips of land between the sea and the higher interior land. Option A is correct because it gives both parts accurately: the sea connection and the relief type, which is low and fairly flat land. Option B is wrong because the Himalayas are high mountains formed on land, not coral islands inside the sea. Option C is wrong because the Northern Plains are inland alluvial plains formed by river deposits; they are not islands in the Arabian Sea. Option D is wrong because the Peninsular Plateau is a raised land region, not a water region of the Bay of Bengal. The words ‘sea’ and ‘coastal’ do not mean the land itself is water; coastal land lies beside the sea. Memory cue: coastal plain = low, fairly flat land beside the sea.
