Answer 1

Hint: The Coastal Plains of India lie on both sides of the Deccan plateau. The coastline runs along with the Eastern ghats and the Western ghats. The coastal Plains runs a distance of about 6,150 km, Rann of Kutch, in the west to West Bengal in the east.

Complete Step by Step answer: The coastline of India includes 13 states and Union Territories. It is divided into 2 types; Eastern Coastal Plains and Western Coastal Plains .The eastern coastal plains of India runs through the Eastern Ghats along the Bay of Bengal. The Mahanadi, Krishna, Godavari and Kaveri rivers form deltas in this region. These deltas are very fertile. The delta formed by river Krishna is called the ‘Granary of South India‘. It is divided into 3 categories:
-Utkal coast which extends between the Chilika Lake and Kolleru Lake.
-Andhra coast which extends between the Kolleru Lake and Pulicat Lake.
-Coromandel coast which extends between Pulicat Lake and Kanyakumari in Tamil Nadu. This coastline remains dry in summer seasons and receives rainfall from the north-east monsoons during the winters.
The western coastal plains runs through the Western Ghats along the Arabian sea. It is narrower as compared to the eastern coast.It is divided into 3 categories:
-Konkan coast which extends between Daman in the north to Goa in the south.
-Kanada coast which extends between Marmagaon and Mangalore.
-Malabar coast which extends between Mangalore to Kanyakumari.
Considering the above options, the Kannada coastal plain and Malabar coastal plain are a part of the western coastal plain. Northern Circars and Coromandel coast are a part of the eastern coastal plains. The Coromandel coast lies towards the southern part of river Krishna whereas the Northern Circars lie towards the north.

Hence, option 'a' is correct.

Note: While answering this don't get confused between the Coromandel coast plain and the Northern circars. The Northern Circars lie towards the north of river Krishna.The coastal plains in India are mostly covered with fertile soils which are best for the cultivation of rice. They are rich in marine ecosystems which include coral reefs, estuaries and lagoons.
