Select the answer using the code given below:
(a) 1 only
(b) 1 and 2
(c) 2 and 3
(d) 3 only

Answer : B

Explanation:

Statement I is correct: The western coast of the Peninsular Block (especially Konkan and Malabar coasts) has experienced submergence due to faulting and tectonic movements.
Statement II is correct: The Peninsular Block is characterized by relict and residual hills. The Veliconda Hills, Mahendragiri Hills, Javadi Hills, Palkonda Range, Nallamala Hills, and Aravalli Hills are all explicitly cited as examples of residual mountains within the Peninsular Block.
Statement III is not correct: The Peninsular rivers are mature and typically flow through broad, shallow valleys. Deep, V-shaped valleys are a characteristic of young, fast-flowing Himalayan rivers.
