The correct option is A
Statement 1 is correct: 'Kayals' are backwaters found in the Malabar region of kerala. They are being used for navigation, fishing, and tourism etc.
Statement 2 is incorrect: West coastal plains are an example of submerged coastal plains and therefore provide natural conditions for port and harbor development. The eastern coastal plains are an example of the developing coast that is formed by sediments carried by rivers flowing eastward like the Mahanadi, the Godavari, the Krishna etc. Due to their emergent nature, the eastern coastal plains are not suitable for ports and harbours.
