Statement by statement
Statement 1 is correct: Ever since the Cambrian period, the Peninsular block has stood like a rigid block, with the exception of some of its western coast which is submerged beneath the sea, and some other parts which changed due to tectonic activity without affecting the original basement.
Statement 2 is correct: The residual mountains are also called relict mountains. Examples of residual mountains in India are the Nallamala hills, Mahendragiri hills, the Aravalli hills, the Javadi hills, the Veliconda hills and the Palkonda range.
Statement 3 is not correct: Deep, V-shaped river valleys are formed by the fast-flowing rivers of the Himalayas, not by those of the Peninsular block.
